3x-6=-4\left(-x+2\right)
Use the distributive property to multiply 3 by x-2.
3x-6=-4\left(-x\right)-8
Use the distributive property to multiply -4 by -x+2.
3x-6=4x-8
Multiply -4 and -1 to get 4.
3x-6-4x=-8
Subtract 4x from both sides.
-x-6=-8
Combine 3x and -4x to get -x.
-x=-8+6
Add 6 to both sides.
-x=-2
Add -8 and 6 to get -2.
x=2
Multiply both sides by -1.
