Mathematical sbi contest #3

(Edited)

Here you can keep your brain fit by solving math related problems and also earn SBI by doing so.
The problems usually contain a mathematical equation that in my opinion is fun to solve or has an interesting solution.
I will also only choose problems that can be solved without additional tools, so don't grab your calculator, you won't need it.

Rules

No upvote, No resteem, No follow required!

I will give 1 SBI to a random person who put a correct solution of the problem in a comment.

You have 48 hours to solve it.

In case there are multiple solutions, you have a higher chance of winning if you get all of them correctly.

Problem

To remove the obvious solution, I add an additional condition here:
x ≠ y
And one more thing: I only want integer solutions.
