Is the answer (x-2) (or should I say x+1?)?
Correct me if I've done this wrong, but:

Actually, it seems I am going about this the wrong way.
I am trying the find an a^-1 in which:
a*a^-1=1 in Z_3.
Is this right? By doing a case by case basis I still cant find a suitable answer.
I'm not sure if I'm allowed to bump this, but it would be nice to have an answer.
