4x+2x+x+4=256
Multiply both sides of the equation by 4, the least common multiple of 2,4.
6x+x+4=256
Combine 4x and 2x to get 6x.
7x+4=256
Combine 6x and x to get 7x.
7x=256-4
Subtract 4 from both sides.
7x=252
Subtract 4 from 256 to get 252.
x=\frac{252}{7}
Divide both sides by 7.
x=36
Divide 252 by 7 to get 36.
