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.

If you plotted y = x +5 and y = x on a graph, you would get two parallel lines that never intersect. There are therefore no slutions. There is no x for which the y values are the same

Jen's answer is equally valid
