-\frac{9+2}{3}-5+\frac{2}{3}
Multiply 3 and 3 to get 9.
-\frac{11}{3}-5+\frac{2}{3}
Add 9 and 2 to get 11.
-\frac{11}{3}-\frac{15}{3}+\frac{2}{3}
Convert 5 to fraction \frac{15}{3}.
\frac{-11-15}{3}+\frac{2}{3}
Since -\frac{11}{3} and \frac{15}{3} have the same denominator, subtract them by subtracting their numerators.
-\frac{26}{3}+\frac{2}{3}
Subtract 15 from -11 to get -26.
\frac{-26+2}{3}
Since -\frac{26}{3} and \frac{2}{3} have the same denominator, add them by adding their numerators.
\frac{-24}{3}
Add -26 and 2 to get -24.
-8
Divide -24 by 3 to get -8.
