 # 20h+15=25h

## Enter Equation or Inequality

Solve the following equation
20h+15=25h

Solve for h
20h + 15 = 25h

## Group variables:

Group our variables 20h and 25h
subtract 25h from both sides
20h + 15 - 25h = 25h - 25h

-5h + 15 = 0

## Group constants:

Group our constants 15 and 0.
subtract 15 from both sides
-5h + 15 - 15 = 0 - 15

-5h = -15

## Divide each side of the equation by -5

 -5h -5
 =
 -15 -5

h = 3

h = 3
