x=24

↓Steps Explained:↓

Solve for x

x + 72 = 4x

Group variables

Group our variables x and 4x
subtract 4x from both sides

x + 72 - 4x = 4x - 4x

Cancel 4x on the right side:

-3x + 72 = 0

Group constants

Group our constants 72 and 0.
subtract 72 from both sides

-3x + 72 - 72 = 0 - 72

Cancel 72 on the left side:

-3x = -72

-3x
-3
=
  
-72
-3

x = 24
