It's false because when you have two whole numbers such as 5 and 2, under division it becomes 5/2 (or 2 1/2), which is no longer a whole number.

What happens when you subtract x from both sides? It doesn't work. Plug in any number to see why. If x=1, then x+5=6. X always has to equal x and nothing else, so there are no solutions to this.
