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