Mathematical sbi contest #4
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.
Solutions can sometimes also be general like x = 20, y > -1
. If there are multiple solutions submitted, that are part of the same general solution, they will be counted as one solution.
And one more thing: I only want integer solutions!

Problem
No further restrictions today. The solutions are difficult enough to find.

You can take a look at the results of the last contest here.
To everyone who already participated in a past contest, come back today and try a new problem(tell me if you don't want to be tagged):

In case no one gets a result(which I doubt), I will give away the 1 SBI to anyone who comments.
The contest is over. You can find the results here.
x = 1, y = 2
or
x = 2, y = 1
or
x = 2, y = 2
or
x = 1, y = 1
or
wait, what was the question? I'll answer True!
No, this equation is not true for any values of x and y. If that were the case I wouldn't have chosen it.
By the way even your list of four pairs of x and y already contains a wrong pair. I suggest you rethink your answer.
Oh, right... x can't be 1, and y 2. Also forgot, x = 0, y = 1
The results can be found here.
x, y = 2

Thanks for your entry.
The results can be found here.
-∞<x<∞; y=1
x=2; y=2
Edit Added x=0,y>0
∞<x<∞
? You know that is equivalent to "There is no possible value for x?"Oh yeah I forgot a minus. I meant -∞<x<∞ just any integer x.
The results can be found here.
x=2,y=2
2*2=2 * 2
