6=n\times \frac{3}{5+4}
Add 2 and 3 to get 5.
6=n\times \frac{3}{9}
Add 5 and 4 to get 9.
6=n\times \frac{1}{3}
Reduce the fraction \frac{3}{9} to lowest terms by extracting and canceling out 3.
n\times \frac{1}{3}=6
Swap sides so that all variable terms are on the left hand side.
n=6\times 3
Multiply both sides by 3, the reciprocal of \frac{1}{3}.
n=18
Multiply 6 and 3 to get 18.
