In this question, you're solving for a.

Solve for a:

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

<em>use the distributive property</em>

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

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

<em>combine like terms</em>

-8 + 8a = -8 + 3a

<em>subtract 3a from both sides</em>

-8 + 5a = -8

<em>add 8 to both sides</em>

5a = 0

<em>divide both sides by 5</em>

a = 0
