-6+3x=2x-4-x
Use the distributive property to multiply -3 by 2-x.
-6+3x=x-4
Combine 2x and -x to get x.
-6+3x-x=-4
Subtract x from both sides.
-6+2x=-4
Combine 3x and -x to get 2x.
2x=-4+6
Add 6 to both sides.
2x=2
Add -4 and 6 to get 2.
x=\frac{2}{2}
Divide both sides by 2.
x=1
Divide 2 by 2 to get 1.
