504=n\left(252+72\right)
Multiply both sides of the equation by 2.
504=n\times 324
Add 252 and 72 to get 324.
n\times 324=504
Swap sides so that all variable terms are on the left hand side.
n=\frac{504}{324}
Divide both sides by 324.
n=\frac{14}{9}
Reduce the fraction \frac{504}{324} to lowest terms by extracting and canceling out 36.
