**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.
