Question

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

Answer 1

Answer:

a=8

Step-by-step 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

$\frac{-96}{-12}=\frac{-12a}{-12}$

$a=8$
