2-2x-3\left(2x-1\right)-\left(1+x\right)=8
Use the distributive property to multiply 2 by 1-x.
2-2x-6x+3-\left(1+x\right)=8
Use the distributive property to multiply -3 by 2x-1.
2-8x+3-\left(1+x\right)=8
Combine -2x and -6x to get -8x.
5-8x-\left(1+x\right)=8
Add 2 and 3 to get 5.
5-8x-1-x=8
To find the opposite of 1+x, find the opposite of each term.
4-8x-x=8
Subtract 1 from 5 to get 4.
4-9x=8
Combine -8x and -x to get -9x.
-9x=8-4
Subtract 4 from both sides.
-9x=4
Subtract 4 from 8 to get 4.
x=\frac{4}{-9}
Divide both sides by -9.
x=-\frac{4}{9}
Fraction \frac{4}{-9} can be rewritten as -\frac{4}{9} by extracting the negative sign.
