%28x%2B3%29%2F%28x-5%29+=+%2856-3x%29%2F%28x%5E2-13x%2B40%29
%28x%2B3%29%2F%28x-5%29+=+%2856-3x%29%2F%28%28x-5%29%28x-8%29%29
%28x%2B3%29%2Fcross%28%28x-5%29%29=%2856-3x%29%2F%28cross%28%28x-5%29%29%28x-8%29%29
%28x%2B3%29=%2856-3x%29%2F%28x-8%29%29
%28x%2B3%29%28x-8%29=56-3x
x%5E2-5x-24=56-3x
x%5E2-2x-80=0
%28x-10%29%28x%2B8%29=0
Two solutions:
x-10=0
highlight%28x=10%29
