Question

How to do: -8(1-a)=-7-(1-3a)

Answer 1

In this question, you're solving for a.

Solve for a:

-8(1 - a) =-7 -(1 - 3a)

use the distributive property

-8 + 8a = -7 -(1 - 3a)

-8 + 8a = -7 - 1 + 3a

combine like terms

-8 + 8a = -8 + 3a

subtract 3a from both sides

-8 + 5a = -8

add 8 to both sides

5a = 0

divide both sides by 5

a = 0
