## Introduction

An equation can be termed as a statement of equality between two mathematical expressions containing one or more variables. The expressions are formed by performing operations like addition, subtraction, multiplication and division on the variables.

Note

If we interchange the positions of expressions before and after equality sign, the equation remain same.

For example:

7Y + 5= 8

8 = 7Y + 5

#### Forming Equations with Statements

Form the equation:

The sum of 6 times of an unknown number when added with 12 gives 24.

Solution:

Let the number be ‘x’

6x + 12 = 24 will be our equation.

Balanced equation

• In a balanced equation the left-hand side(LHS) is equal to the right-hand side(RHS).
• Adding, subtracting, multiplying, or dividing both sides by the same number does not affect the equation.
