Is Steve's work correct? Why or why not?

Answer:
B. No, Steve should have added 5 to both sides instead of subtracting 5.
Explanation:
Adding five to both sides would get rid of the -5 on the left side, which isolates the variable. Steve's work is not correct, eliminating choice A. Subtracting 9 would add another term to the equation, which is unnecesary. Choice B is the only answer left.
