10%2F%285x-5%29+%2B+1%2F5+=+2%2F%28x-1%29
the values that make the denominators zero:
5x-5=0...=>..5x=5=>..x=5%2F5=>..x=1
x-1=0=>..x=1

%2810+%2B+1%285x-5%29%29%2F5%285x-5%29+=+2%2F%28x-1%29
%2810+%2B+5x-5%29%2F5%285x-5%29+=+2%2F%28x-1%29
%285x%2B5%29%2F5%285x-5%29+=+2%2F%28x-1%29
5%28x%2B1%29%2F5%285x-5%29+=+2%2F%28x-1%29
%28x%2B1%29%2F%285x-5%29+=+2%2F%28x-1%29.........cross multiply

%28x%2B1%29%28x-1%29+=+2%285x-5%29
x%5E2-1+=+10x-10
x%5E2-1-10x%2B10=0
x%5E2-10x%2B9=0
