X + 2X = 3X
3X = 40
3X/3 = 40/3
X = 40/3

x + 2x = 40 remember that x means 1x
3x = 40 combined x and 2x on the left.
3x/3 = 40/3 divide by 3 on both sides (to undo mult. by 3)
x = 13 1/3 or 40/3 actually divided...or leave it as fraction

3x = 40 divide the both sides by 3
x = 40 / 3
= 13 1/3

Step 1: Combine like terms, i.e. add all the X terms to get a single coefficient behind the X.
Step 2: Reduce the X coefficient to 1 by dividing both sides of the equation by the proper coefficient.
Good luck.

rewriting you have 3x=40, or x=1.333...
