2x-4=-\left(4-x\right)
Use the distributive property to multiply 2 by x-2.
2x-4=-4-\left(-x\right)
To find the opposite of 4-x, find the opposite of each term.
2x-4=-4+x
The opposite of -x is x.
2x-4-x=-4
Subtract x from both sides.
x-4=-4
Combine 2x and -x to get x.
x=-4+4
Add 4 to both sides.
x=0
Add -4 and 4 to get 0.
