# 50+7.50p=140

## Enter Equation or Inequality

Solve the following equation
50+7.50p=140

Solve for p
50 + 7.50p = 140

## Group constants

Group our constants 50 and 140.
subtract 50 from both sides
7.50p + 50 - 50 = 140 - 50

7.50p = 90

## Divide each side of the equation by 7.50

 7.50p 7.50
 =
 90 7.5

p = 12

p = 12
