Only one last step or two if you choose to go the other way.

Answer 35

Oh no. I didn't know I was helping you cheat. I really think in the future you should take your tests using your own knowledge even if behind. A test is to test one's on knowledge.

Answer 36

this and one other question is really all i asked help with. it was only because i was two lessons behind but now im fine with my algebra lessons, everything else i did alone so it wasnt really cheating because you helped and explained it to me so thnk you for that
