4x-8-x-4=4-x
To find the opposite of x+4, find the opposite of each term.
3x-8-4=4-x
Combine 4x and -x to get 3x.
3x-12=4-x
Subtract 4 from -8 to get -12.
3x-12+x=4
Add x to both sides.
4x-12=4
Combine 3x and x to get 4x.
4x=4+12
Add 12 to both sides.
4x=16
Add 4 and 12 to get 16.
x=\frac{16}{4}
Divide both sides by 4.
x=4
Divide 16 by 4 to get 4.
