using elimination, the best first step is multiply the first equation by -3. multiply the second equation by 3 doesn't do anything to eliminate one of the unknowns. solving for x in the first equation or solving for y in the second equation are the substitution method, not the elimination method.
I took the test and got it right, if you use my answer and get it wrong. You have a different question, I used the guys answer above and it was incorrect.
