Agh... Sorry... Now I screwed up everyone's answers... It wasn't a negative sign... Hehe... It was just a hyphen... I guess it wasn't the best place to put a hyphen... Edit: On the first one, I reworked it and got it. On the second one, I have a friend helping me. No need to work these anymore unless you need to. Btw, -17/18 was the answer to the first one so I was originally right... Sorry for the "-" sign mix up...
