4x+4=4+x-3
Multiply both sides of the equation by 4.
4x+4=1+x
Subtract 3 from 4 to get 1.
4x+4-x=1
Subtract x from both sides.
3x+4=1
Combine 4x and -x to get 3x.
3x=1-4
Subtract 4 from both sides.
3x=-3
Subtract 4 from 1 to get -3.
x=\frac{-3}{3}
Divide both sides by 3.
x=-1
Divide -3 by 3 to get -1.
