9x-\frac{9}{2}+\frac{x}{3}+\frac{1}{2}
Divide 27x by 3 to get 9x.
\frac{28}{3}x-\frac{9}{2}+\frac{1}{2}
Combine 9x and \frac{x}{3} to get \frac{28}{3}x.
\frac{28}{3}x+\frac{-9+1}{2}
Since -\frac{9}{2} and \frac{1}{2} have the same denominator, add them by adding their numerators.
\frac{28}{3}x+\frac{-8}{2}
Add -9 and 1 to get -8.
\frac{28}{3}x-4
Divide -8 by 2 to get -4.
