12x+1>12x+4-x+8
Use the distributive property to multiply 4 by 3x+1.
12x+1>11x+4+8
Combine 12x and -x to get 11x.
12x+1>11x+12
Add 4 and 8 to get 12.
12x+1-11x>12
Subtract 11x from both sides.
x+1>12
Combine 12x and -11x to get x.
x>12-1
Subtract 1 from both sides.
x>11
Subtract 1 from 12 to get 11.
