70=140p
Variable p cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by p.
140p=70
Swap sides so that all variable terms are on the left hand side.
p=\frac{70}{140}
Divide both sides by 140.
p=\frac{1}{2}
Reduce the fraction \frac{70}{140} to lowest terms by extracting and canceling out 70.
