Question

-90 = -2(6a – 3)
Pls help just solving an equation. :)

Answer 1

a=8

Explanation:

We are asked to solve this equation -90=-2(6a-3) . As here our variable is a , we will solve it for a. Let us do it step by step

1. Opening the brackets and distribution of -2 inside

-90=-12a+6

2. Subtracting 6 from both sides we get

-90-6=-12a+6-6

-96=-12a

3. Dividing both sides by 12 we get

`(-96)/(-12)=(-12a)/(-12)`

`a=8`
