Can I cancel these out? (-1+x)/(x-1) I cannot remember if I can do this? If I put a number in for x I get the same values so they will give me one. So I believe that I can with out any problems. I am just having a brain fart today. Thank you

Yes, (-1+x)=(x-1) take -3+x=4 for example we know the answer of this is 7. x-3=4 The answer remains 7.
