Question

I can figure out how to break this down..

Answer 1

`( ((2)/(x) -1))/( ((1)/(x) -1))= (( (2-x)/(x)))/(( (1-x)/(x))) = (2-x)/(1-x)`. Now the answers on your paper do not have this choice, but if you think about it, (2-x)=-1(x-2) and (1-x)=-1(x-1). This means that when you have (2-x)/(1-x), this also equals to (x-2)/(x-1), since the -1's cancel out. So, the answer is D.

I hope this was helpful!
