20p+70-60p=20
Subtract 60p from both sides.
-40p+70=20
Combine 20p and -60p to get -40p.
-40p=20-70
Subtract 70 from both sides.
-40p=-50
Subtract 70 from 20 to get -50.
p=\frac{-50}{-40}
Divide both sides by -40.
p=\frac{5}{4}
Reduce the fraction \frac{-50}{-40} to lowest terms by extracting and canceling out -10.
