12p-9-14p=-30
Subtract 14p from both sides.
-2p-9=-30
Combine 12p and -14p to get -2p.
-2p=-30+9
Add 9 to both sides.
-2p=-21
Add -30 and 9 to get -21.
p=\frac{-21}{-2}
Divide both sides by -2.
p=\frac{21}{2}
Fraction \frac{-21}{-2} can be simplified to \frac{21}{2} by removing the negative sign from both the numerator and the denominator.
