Look For Keywords In The Algebra Word Problems That Can Signal Which Operation You Will Be Doing
These keywords can go a long way in helping you determine how to set up the algebra equations. Heres a list of some common keywords to get you started:
- Addition: added to, combined, increased by, more than, sum, total
- Subtraction: decreased by, difference of, less than
- Multiplication: increased by a factor of, multiplied by, times
- Division: out of, per, ratio of
- Equals: are, gives, is, will be
Note that these keywords are not a complete list you will definitely see other words used to mean these operations, but keep in mind how the numbers and variables are positioned and what is being asked, and you should be able to add to this keyword list yourself!
Also, be sure to pay close attention to the relationship of the two variables when it comes to division and subtraction. It matters which variable comes first, and when the algebra word problem asks for the difference between x and y, when you write the algebra out, you will show x y. Likewise, the ratio of x and y written out will show x / y.

Algebra Problems For Class 6
In class 6, students will be introduced with an algebra concept. Here, you will learn how the unknown values are represented in terms of variables. The given expression can be solved only if we know the value of unknown variable. Let us see some examples.
Example: Solve, 4x + 5 when, x = 3.
Solution: Given, 4x + 5
Now putting the value of x=3, we get
4 + 5 = 12 + 5 = 17.
Example: Give expressions for the following cases:
12 added to 2x
6 multiplied by y
25 subtracted from z
17 times of m
Solutions To The Algebra Problems
Solutions and explanations for each of the answers to the algebra practice problems are provided in this section.
Polynomials are algebraic expressions that contain more than one term.
You will definitely have questions on your algebra exam about multiplying polynomials.
When multiplying polynomials, you should use the F-O-I-L method.
This means that you multiply the variables two at a time from each of the two parts of the equation in the parentheses in this order:
First Outside Inside Last
So, the first variables in each set of parentheses are 2x and 2x
The variables on the outside of each set of parentheses are 2x and 3y
The variables on the inside of each set of parentheses are -3y and 2x
The last variables in each set of parentheses are -3y and -3y
Then we add all of the above parts together to get:
Algebra practice problems usually include inequalities problems and answers. Inequalities contain the less than or greater than signs.
In order to solve inequalities, deal with the whole numbers on each side of the equation first:
31 2/3x> 27
2/3x > -4
Then deal with the fraction:

Hard Algebra Problem 1.
If $a^2 + b^2 = 1$ and $c^2 + d^2 = 2$ then the value of $^2 + ^2$ is,
First stage Problem analysis:
At first glance the expressions though seem to be a bit complex involving as many as 4 variables, on closer examination of the end state, or the expression to be evaluated, we find a promising clue to the solution.
If we imagine both the squares of sums expanded, the middle terms in each three term expression are transformed to the equal value $2abcd$ and fortunately, in opposite signs. These will then be cancelled out and the problem state will be considerably simplified.
Let us put this thought to practice calling the target expression as $E$ for convenience,
$E= ^2 + ^2 $
$\hspace = $
$\hspace + $,
$ \hspace = + $
Second stage problem analysis:
Now we look at the four terms left out and examine this expression against the given expressions looking for the presence of expressions $a^2 + b^2$ and $c^2 + d^2$ in the current simplified target expression.
We always go through this comparison by following the End State Analysis Approach at every stage of simplification and progress towards solution. At this stage the four term simplified expression is our end state expression.
With this closer examination looking for specific patterns, invariably we find the second clue.
$E = + $
$\hspace = + $
$\hspace = a^2 + b^2$
$E = 2 = 2$
Answer: Option d: 2.

Summary of deductive steps:
The Basic Strategy For Algebraic Equations
The basic strategy for solving any algebraic equation is to first isolate the variable term on one side of the equation, and then apply inverse operations as necessary to strip away any coefficients or exponents. An inverse operation “undoes” another operation for example, division “undoes” the multiplication of a coefficient, and square roots “undo” the squaring operation of a second-power exponent.
Note that if you apply an operation to one side of an equation, you must apply the same operation on the other side of the equation. By maintaining this rule, you can change the way the terms of an equation are written without changing their relation to each other.

Solving Two Equations With Two Variables
If you’re given a system of two equations that have the same two variables in them, this usually means the equations are related and you can use a technique called substitution to find values for both variables. Consider the equation from the last example, plus a second, related equation that uses the same variables:
Choose one equation, and solve that equation for one of the variables. In this case, use what you already know about the first equation from the previous example, which you already solved for x:
Substitute the result from Step 1 into the other equation. In other words, substitute the value /5 for any instances of x in the other equation. This gives you an equation with just one variable:
Simplify the equation from Step 2 and solve for the remaining variable, which in this case is y.
Start by multiplying both sides by 5:
This simplifies to:
How Do You Do Algebra Problems
Algebra word problems can be tricky to solve, but there are all kinds of resources that can help you out.

Solving One Equation With Two Variables
If you have one equation with two variables, you’ll probably be asked to solve for just one of those variables. In that case you follow much the same procedure as you’d use for any algebraic equation with one variable. Consider the example
if you’re asked to solve for x.
Subtract 3 from each side of the equation, leaving the x term by itself on one side of the equal sign:
Divide both sides of the equation by 5 to remove the coefficient from the x term:

Algebra Problems For Class 7
In class 7, students will deal with algebraic expressions like x+y, xy, 32×2-12y2, etc. There are different kinds of the terminology used in case algebraic equations such as
Let us understand these terms with an example. Suppose 4x + 5y is an algebraic expression, then 4x and 5y are the terms. Since here the variables used are x and y, therefore, x and y are the factors of 4x + 5y. And the numerical factor attached to the variables are the coefficient such as 4 and 5 are the coefficient of x and y in the given expression.
Any expression with one or more terms is called a polynomial. Specifically, a one-term expression is called a monomial a two-term expression is called a binomial, and a three-term expression is called a trinomial.
Terms which have the same algebraic factors are like terms. Terms which have different algebraic factors are unlike terms. Thus, terms 4xy and 3xy are like terms but terms 4xy and 3x are not like terms.
Example: Add 3x + 5x
Solution: Since 3x and 5x have the same algebraic factors, hence, they are like terms and can be added by their coefficient.
3x + 5x = 8x
Example: Collect like terms and simplify the expression: 12×2 9x + 5x 4×2 7x + 10.
Solution: 12×2 9x + 5x 4×2 7x + 10
= x2 9x + 5x 7x + 10
= 8×2 11x + 10
