-4%2F%282x%2B3%29%2B1%2F%28x-1%29=1%2F%282x%2B3%29%28x-1%29

%28-4%28x-1%29%2B1%282x%2B3%29%29%2F%282x%2B3%29%28x-1%29=1%2F%282x%2B3%29%28x-1%29

%28-4x%2B4%2B2x%2B3%29%2F%282x%2B3%29%28x-1%29=1%2F%282x%2B3%29%28x-1%29

%28-2x%2B7%29%2F%282x%2B3%29%28x-1%29=1%2F%282x%2B3%29%28x-1%29........if denominators same => nominators are same too

-2x%2B7=1
7=1%2B2x
7-1=2x
6=2x
3=x
