Math Contest #11 [1 SBI]

in puzzle •  2 months ago 

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(at least not if you can calculate basic stuff in your head), so don't grab your calculator, you won't need it.

Every friday and tuesday!



No upvote, No resteem, No follow required!

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

You have 72 hours to solve it.

Some additional rules for the case that the problem is an equation or a collection of equations.

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: If there are infinitely many solutions, I only want integer solutions!

Although it has no trivial solutions like 1 or 0, it should be easy to solve.

You can take a look at the results of the last contest here. There you can also find out how I evaluate your entries.

Looks good, however I expect you to find all 4 solutions next time.
Always remember to write ± in front of every root.

Fu##! This was really tricky.
I come to the result that x as well as y are +-0.707 (or +/- square root of 0.5).
