3x-4-\left(-2x\right)=x+8
To find the opposite of 4-2x, find the opposite of each term.
3x-4+2x=x+8
The opposite of -2x is 2x.
5x-4=x+8
Combine 3x and 2x to get 5x.
5x-4-x=8
Subtract x from both sides.
4x-4=8
Combine 5x and -x to get 4x.
4x=8+4
Add 4 to both sides.
4x=12
Add 8 and 4 to get 12.
x=\frac{12}{4}
Divide both sides by 4.
x=3
Divide 12 by 4 to get 3.
