In this question, you're solving for a.

Solve for a:

-84 = 6(4a - 2)

<em>Distribute the 6 to the variables inside the parenthesis</em>

-84 = 24a - 12

<em>Add 12 to both sides</em>

-72 = 24a

<em>Divide both sides by 24</em>

-3 = a

This means that answer choice D would be the correct answer.

Answer:

D). -3
