2\left(3x+4\right)+5-x=4x+12
Multiply both sides of the equation by 4, the least common multiple of 2,4.
6x+8+5-x=4x+12
Use the distributive property to multiply 2 by 3x+4.
6x+13-x=4x+12
Add 8 and 5 to get 13.
5x+13=4x+12
Combine 6x and -x to get 5x.
5x+13-4x=12
Subtract 4x from both sides.
x+13=12
Combine 5x and -4x to get x.
x=12-13
Subtract 13 from both sides.
x=-1
Subtract 13 from 12 to get -1.
