Subtract. Simplify, if possible.
%287-x%29%2F%28x-3%29-%282x-9%29%2F%283-x%29
We can make the denominators the same by factoring out -1 on the second denominator
%287-x%29%2F%28x-3%29-%282x-9%29%2F%28-1%28x-3%29%29
Which changes the sign to
%287-x%29%2F%28x-3%29%2B%282x-9%29%2F%28x-3%29
:
%28%287-x%29%2B%282x-9%29%29%2F%28x-3%29 = %28x+-+2%29%2F%28x-3%29
