Answer:
Q equals 1.
Explanation:
We want to isolate q. We can do this by moving the terms with variables to one side and the terms with no variables to the other side. Start by subtracting both sides by 12. This gives us 9q = 13 + 8q - 12. Subtract both sides by 8q. 9q - 8q = 13 - 12. Now, subtract. 9q-8q=q and 13-12=1. q=1.
