9=13-7p+720
Combine -3p and -4p to get -7p.
9=733-7p
Add 13 and 720 to get 733.
733-7p=9
Swap sides so that all variable terms are on the left hand side.
-7p=9-733
Subtract 733 from both sides.
-7p=-724
Subtract 733 from 9 to get -724.
p=\frac{-724}{-7}
Divide both sides by -7.
p=\frac{724}{7}
Fraction \frac{-724}{-7} can be simplified to \frac{724}{7} by removing the negative sign from both the numerator and the denominator.
