If you are given an equation with brackets, one way to solve it is to multiply out the brackets. Follow the example below:

Solve the equation: 2(a + 5) = 16

1. Multiply out the brackets and remember that everything inside the brackets will get multiplied by 2.

× a + 2 × 5 = 16

You get: 2a + 10 = 16

2. Next, do the inverse of + 10, so subtract 10 from both sides.

2a + 10 - 10 = 16 - 10

So 2a = 6

3. To find out what a is you need to do the inverse of multiplying by 2 which is dividing by 2.

So a = 3
