-2x+3=5-4x+2
Use the distributive property to multiply -2 by 2x-1.
-2x+3=7-4x
Add 5 and 2 to get 7.
-2x+3+4x=7
Add 4x to both sides.
2x+3=7
Combine -2x and 4x to get 2x.
2x=7-3
Subtract 3 from both sides.
2x=4
Subtract 3 from 7 to get 4.
x=\frac{4}{2}
Divide both sides by 2.
x=2
Divide 4 by 2 to get 2.
