x-2\left(x-3x+3\right)=8
Use the distributive property to multiply -3 by x-1.
x-2\left(-2x+3\right)=8
Combine x and -3x to get -2x.
x+4x-6=8
Use the distributive property to multiply -2 by -2x+3.
5x-6=8
Combine x and 4x to get 5x.
5x=8+6
Add 6 to both sides.
5x=14
Add 8 and 6 to get 14.
x=\frac{14}{5}
Divide both sides by 5.
