Second Equation!

Alright, this is our second equation (and second letter)  

I incorporated it into an image to make it less confusing. Note that you are solving for the "x" value and that the area should be found in the process.  

(Edit: Find the maximum area the fence can cover) 

I know this looks weird. It is weird. This question was created by @MaskedMadara so let's give them a round of applause 👏👏👏 (eg. get mad at him not me) 

Once you solve this make sure to find your corresponding letter over at: https://www.chess.com/blog/Max_Wolfe/i-hate-negative-numbers-ill-stop-at-nothing-to-avoid-them

Please keep answers to yourself so as to allow others to solve it for themselves  

If you wish to confirm your answer then feel free to message me privately.

Here's your joke (admit it, you love them):

I poured root beer into a square glass.

Now I just have beer.

🙄 Sorry... 🙄

Good luck!
