p=450-30x
Use the distributive property to multiply 30 by 15-x.
450-30x=p
Swap sides so that all variable terms are on the left hand side.
-30x=p-450
Subtract 450 from both sides.
\frac{-30x}{-30}=\frac{p-450}{-30}
Divide both sides by -30.
x=\frac{p-450}{-30}
Dividing by -30 undoes the multiplication by -30.
x=-\frac{p}{30}+15
Divide p-450 by -30.
p=450-30x
Use the distributive property to multiply 30 by 15-x.
