Answer:To solve for q in the equation -18 + -3q = -63, we need to get q by itself on one side of the equation. We can do this by adding 18 to both sides of the equation:
-18 + -3q + 18 = -63 + 18
Simplifying, we get:
-3q = -45
Then, we can divide both sides of the equation by -3 to solve for q:
(-3q) / -3 = -45 / -3
Simplifying, we get:
q = 15
Therefore, the solution for q is 15.
