8-4x+1=2x+2-5\left(1-4x\right)
Use the distributive property to multiply 4 by 2-x.
9-4x=2x+2-5\left(1-4x\right)
Add 8 and 1 to get 9.
9-4x=2x+2-5+20x
Use the distributive property to multiply -5 by 1-4x.
9-4x=2x-3+20x
Subtract 5 from 2 to get -3.
9-4x=22x-3
Combine 2x and 20x to get 22x.
9-4x-22x=-3
Subtract 22x from both sides.
9-26x=-3
Combine -4x and -22x to get -26x.
-26x=-3-9
Subtract 9 from both sides.
-26x=-12
Subtract 9 from -3 to get -12.
x=\frac{-12}{-26}
Divide both sides by -26.
x=\frac{6}{13}
Reduce the fraction \frac{-12}{-26} to lowest terms by extracting and canceling out -2.
