# 4x-36=-5x

## Enter Equation or Inequality

Solve the following equation
4x-36=-5x

Solve for x
4x - 36 = - 5x

## Group variables

Group our variables 4x and -5x
4x - 36 + 5x = -5x + 5x

9x - 36 = 0

## Group constants

Group our constants -36 and 0.
9x - 36 + 36 = 0 + 36

9x = 36

## Divide each side of the equation by 9

 9x 9
 =
 36 9

x = 4

x = 4
