3x-1%2Bx=3x%2B1%2B4
3x%2Bx-1=3x%2B1%2B4
4x-1=3x%2B5
4x-3x-1=3x-3x%2B5
x-1=0%2B5
x-1=5
x-1%2B1=5%2B1
x%2B0=6
x=6

3x%2B1%2Bx%2F9=3x%2B1%2B4%2F3
9%283x%2B1%2Bx%2F9%29=9%283x%2B1%2B4%2F3%29
27x%2B9%2Bx=27x%2B9%2B12
27x%2Bx%2B9=27x%2B9%2B12
28x%2B9=27x%2B21
28x-27x%2B9=27x-27x%2B21
x%2B9=0%2B21
x%2B9=21
x%2B9-9=21-9
x%2B0=12
x=12
