There are infinite solutions to this.......here's a graph......https://www.desmos.com/calculator/ctfhymw5hv

I I reckon there is probably another condition you have overlooked? I bet you are told that x and y are both positive integers, x,y ∈ {1,2, ....}

The only solution is x=2, y=101 (or vice versa)

So you would express this as: x,y ∈ {2,101}, x≠y
