\frac{-5220}{18}+324=9\left(7-\frac{2\times 18+29}{18}\right)
Multiply -180 and 29 to get -5220.
-290+324=9\left(7-\frac{2\times 18+29}{18}\right)
Divide -5220 by 18 to get -290.
34=9\left(7-\frac{2\times 18+29}{18}\right)
Add -290 and 324 to get 34.
34=9\left(7-\frac{36+29}{18}\right)
Multiply 2 and 18 to get 36.
34=9\left(7-\frac{65}{18}\right)
Add 36 and 29 to get 65.
34=9\left(\frac{126}{18}-\frac{65}{18}\right)
Convert 7 to fraction \frac{126}{18}.
34=9\times \frac{126-65}{18}
Since \frac{126}{18} and \frac{65}{18} have the same denominator, subtract them by subtracting their numerators.
34=9\times \frac{61}{18}
Subtract 65 from 126 to get 61.
34=\frac{9\times 61}{18}
Express 9\times \frac{61}{18} as a single fraction.
34=\frac{549}{18}
Multiply 9 and 61 to get 549.
34=\frac{61}{2}
Reduce the fraction \frac{549}{18} to lowest terms by extracting and canceling out 9.
