-\frac{1}{4}x-\frac{1}{4}\left(-8\right)+\frac{1}{2}\left(x+2\right)=x-3
Use the distributive property to multiply -\frac{1}{4} by x-8.
-\frac{1}{4}x+\frac{-\left(-8\right)}{4}+\frac{1}{2}\left(x+2\right)=x-3
Express -\frac{1}{4}\left(-8\right) as a single fraction.
-\frac{1}{4}x+\frac{8}{4}+\frac{1}{2}\left(x+2\right)=x-3
Multiply -1 and -8 to get 8.
-\frac{1}{4}x+2+\frac{1}{2}\left(x+2\right)=x-3
Divide 8 by 4 to get 2.
-\frac{1}{4}x+2+\frac{1}{2}x+\frac{1}{2}\times 2=x-3
Use the distributive property to multiply \frac{1}{2} by x+2.
-\frac{1}{4}x+2+\frac{1}{2}x+1=x-3
Cancel out 2 and 2.
\frac{1}{4}x+2+1=x-3
Combine -\frac{1}{4}x and \frac{1}{2}x to get \frac{1}{4}x.
\frac{1}{4}x+3=x-3
Add 2 and 1 to get 3.
\frac{1}{4}x+3-x=-3
Subtract x from both sides.
-\frac{3}{4}x+3=-3
Combine \frac{1}{4}x and -x to get -\frac{3}{4}x.
-\frac{3}{4}x=-3-3
Subtract 3 from both sides.
-\frac{3}{4}x=-6
Subtract 3 from -3 to get -6.
x=-6\left(-\frac{4}{3}\right)
Multiply both sides by -\frac{4}{3}, the reciprocal of -\frac{3}{4}.
x=\frac{-6\left(-4\right)}{3}
Express -6\left(-\frac{4}{3}\right) as a single fraction.
x=\frac{24}{3}
Multiply -6 and -4 to get 24.
x=8
Divide 24 by 3 to get 8.
