36=3x-\left(4-x\right)
Subtract 2 from 38 to get 36.
36=3x-4-\left(-x\right)
To find the opposite of 4-x, find the opposite of each term.
36=3x-4+x
The opposite of -x is x.
36=4x-4
Combine 3x and x to get 4x.
4x-4=36
Swap sides so that all variable terms are on the left hand side.
4x=36+4
Add 4 to both sides.
4x=40
Add 36 and 4 to get 40.
x=\frac{40}{4}
Divide both sides by 4.
x=10
Divide 40 by 4 to get 10.
