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.

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.↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓↑↓
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.
