That description makes the equation need to be 4%2F%28x%2B1%29-3%2F%28x%2B2%29=1. The properly placed parentheses are necessary.

Multiply the left side and the right side by (x+1)(x+2), which is the simplest common denominator, and simplify.

4%28x%2B2%29-3%28x%2B1%29=%28x%2B1%29%28x%2B2%29
4x%2B8-3x-3=x%5E2%2B3x%2B2
x%5E2%2B3x%2B2-4x-8%2B3x%2B3=0
x%5E2%2B2x-3=0
%28x-1%29%28x%2B3%29=0


Either x=1 Or x=-3.
