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
[tex]\frac{-96}{-12}=\frac{-12a}{-12}[/tex]
[tex]a=8[/tex]
