**About**

When there is just one variable in the equation which has an exponent of 1, it is known as Linear equation.

**Example: **

15x = x–7

In order to solve linear equations we need to isolate the variable

**Demonstration**

1) One step operation

Y - 3 = 15

**Solution:**

This time, 3 is being subtracted from y. So, we will undo that by adding 3 to both sides.

Y – 3 + 3 = 15 +3

Y = 18

2) Two Step Operation

5x - 2 =15

**Solution:**

Adding 2 to both sides:

5x - 2 =15

5x -2 + 2= 15+2

5x =15

Now divide both sides by 5

5x /5= 15/ 5

X=3
