\frac{1}{2}x+\frac{1}{2}\left(-1\right)-\frac{1}{3}\left(3x-6\right)=\frac{1}{4}\left(2x-8\right)
Use the distributive property to multiply \frac{1}{2} by x-1.
\frac{1}{2}x-\frac{1}{2}-\frac{1}{3}\left(3x-6\right)=\frac{1}{4}\left(2x-8\right)
Multiply \frac{1}{2} and -1 to get -\frac{1}{2}.
\frac{1}{2}x-\frac{1}{2}-\frac{1}{3}\times 3x-\frac{1}{3}\left(-6\right)=\frac{1}{4}\left(2x-8\right)
Use the distributive property to multiply -\frac{1}{3} by 3x-6.
\frac{1}{2}x-\frac{1}{2}-x-\frac{1}{3}\left(-6\right)=\frac{1}{4}\left(2x-8\right)
Cancel out 3 and 3.
\frac{1}{2}x-\frac{1}{2}-x+\frac{-\left(-6\right)}{3}=\frac{1}{4}\left(2x-8\right)
Express -\frac{1}{3}\left(-6\right) as a single fraction.
\frac{1}{2}x-\frac{1}{2}-x+\frac{6}{3}=\frac{1}{4}\left(2x-8\right)
Multiply -1 and -6 to get 6.
\frac{1}{2}x-\frac{1}{2}-x+2=\frac{1}{4}\left(2x-8\right)
Divide 6 by 3 to get 2.
-\frac{1}{2}x-\frac{1}{2}+2=\frac{1}{4}\left(2x-8\right)
Combine \frac{1}{2}x and -x to get -\frac{1}{2}x.
-\frac{1}{2}x-\frac{1}{2}+\frac{4}{2}=\frac{1}{4}\left(2x-8\right)
Convert 2 to fraction \frac{4}{2}.
-\frac{1}{2}x+\frac{-1+4}{2}=\frac{1}{4}\left(2x-8\right)
Since -\frac{1}{2} and \frac{4}{2} have the same denominator, add them by adding their numerators.
-\frac{1}{2}x+\frac{3}{2}=\frac{1}{4}\left(2x-8\right)
Add -1 and 4 to get 3.
-\frac{1}{2}x+\frac{3}{2}=\frac{1}{4}\times 2x+\frac{1}{4}\left(-8\right)
Use the distributive property to multiply \frac{1}{4} by 2x-8.
-\frac{1}{2}x+\frac{3}{2}=\frac{2}{4}x+\frac{1}{4}\left(-8\right)
Multiply \frac{1}{4} and 2 to get \frac{2}{4}.
-\frac{1}{2}x+\frac{3}{2}=\frac{1}{2}x+\frac{1}{4}\left(-8\right)
Reduce the fraction \frac{2}{4} to lowest terms by extracting and canceling out 2.
-\frac{1}{2}x+\frac{3}{2}=\frac{1}{2}x+\frac{-8}{4}
Multiply \frac{1}{4} and -8 to get \frac{-8}{4}.
-\frac{1}{2}x+\frac{3}{2}=\frac{1}{2}x-2
Divide -8 by 4 to get -2.
-\frac{1}{2}x+\frac{3}{2}-\frac{1}{2}x=-2
Subtract \frac{1}{2}x from both sides.
-x+\frac{3}{2}=-2
Combine -\frac{1}{2}x and -\frac{1}{2}x to get -x.
-x=-2-\frac{3}{2}
Subtract \frac{3}{2} from both sides.
-x=-\frac{4}{2}-\frac{3}{2}
Convert -2 to fraction -\frac{4}{2}.
-x=\frac{-4-3}{2}
Since -\frac{4}{2} and \frac{3}{2} have the same denominator, subtract them by subtracting their numerators.
-x=-\frac{7}{2}
Subtract 3 from -4 to get -7.
x=\frac{7}{2}
Multiply both sides by -1.
