3x-2x-\left(-4\right)+3=-2x+4
To find the opposite of 2x-4, find the opposite of each term.
3x-2x+4+3=-2x+4
The opposite of -4 is 4.
x+4+3=-2x+4
Combine 3x and -2x to get x.
x+7=-2x+4
Add 4 and 3 to get 7.
x+7+2x=4
Add 2x to both sides.
3x+7=4
Combine x and 2x to get 3x.
3x=4-7
Subtract 7 from both sides.
3x=-3
Subtract 7 from 4 to get -3.
x=\frac{-3}{3}
Divide both sides by 3.
x=-1
Divide -3 by 3 to get -1.
