%28x-1%29%2F%28x%2B3%29=2
Use the common denominator x%2B3
%28x-1%29%2F%28x%2B3%29=%282%28x%2B3%29%29%2F%28x%2B3%29
%28x-1%29%2F%28x%2B3%29-%282%28x%2B3%29%29%2F%28x%2B3%29=0
%28x-1-2%28x%2B3%29%29%2F%28x%2B3%29=0
%28x-1-2x-6%29%29%2F%28x%2B3%29=0
%28-x-7%29%2F%28x%2B3%29=0
-%28x%2B7%29%2F%28x%2B3%29=0
The expression equals zero only when,
x%2B7=0
highlight%28x=-7%29
