Jada solved the equation -g - 108 for x using the steps below. What was Jada's error?

Answer: Choice A) Jada should have multiplied both sides by 108.
Reasoning:
x is a placeholder for some unknown value. We are dividing x by 108 to form the fraction x/108. To isolate x, we need to undo this operation. So we need to multiply both sides by 108. Doing so leads to the solution x = -48.
