i knew i have seen this question before i just answered this one yesterday, you must be in the same class..lol
first find common denominator
which in this case simply multiply the 2 denominators together to get %287-x%29%28x%2B7%29
%286%2F%287-x%29%29%2B%285%2F%28x%2B7%29%29


%28%2877%2Bx%29%2F%28%28x%2B7%29%287-x%29%29%29
