1/3x = x - 22.
That is the equation that you use, to find the number. Subtract 1/3x from x to get 0= 2/3x -22. Yes, it is possible to have 0 on one side in certain instances. The next thing you do is add 22 to both sides to get 22= 2/3x. Finally, divide both sides by 2/3 and you get 33 = x or x = 33. If you don't believe me, substitute x for 33. 11 = 11. I hope this helps in any way, and have a nice day!
