%2812%2Bx%29%2B%284%288-x%29%29%2F3-2x=16%2Bx
If you multiply both sides by 3,
3%28%2812%2Bx%29%2B%284%288-x%29%29%2F3-2x%29%29%29=3%2816%2Bx%29
%283%2812%2Bx%29%2B4%288-x%29%29=3%2816%2Bx%29
3%28x%2B12%29%2B4%28-x%2B8%29=3%28x%2B16%29
%283x%2B36%29%2B%28-4x%2B32%29=3x%2B48
%283x-4x%29%2B%2836%2B32%29=3x%2B48
-x%2B68=3x%2B48
3x%2B48=-x%2B68
3x%2Bx%2B48=-x%2Bx%2B68
4x%2B48=0%2B68
4x%2B48=68
4x%2B48-48=68-48
4x%2B0=20
4x=20
4x%2F4=20%2F4
x=5
