-2\left(-x\right)+8=3x-3
Use the distributive property to multiply -2 by -x-4.
2x+8=3x-3
Multiply -2 and -1 to get 2.
2x+8-3x=-3
Subtract 3x from both sides.
-x+8=-3
Combine 2x and -3x to get -x.
-x=-3-8
Subtract 8 from both sides.
-x=-11
Subtract 8 from -3 to get -11.
x=11
Multiply both sides by -1.
