8 = 4(q - 2) + 4
Here, you are trying to solve for q.
The first step is distributing. Multiply 4 by everything inside the parentheses.
8 = (4*q) + (4*-2) + 4
8 = 4q - 8 + 4
Now combine like terms.
8 = 4q - 4
Add 4 to both sides.
12 = 4q
And last, divide both sides by 4.
3 = q
The answer to this equation is q = 3.
