Hey I was reading some comics and in the comics the protagonist tells someone to solve this equation if he wants him to do as he says.

I was wondering if it's possible to solve or is it just a joke. I played around a bit by getting the ln integral and putting the result together again as a ln and writing it as e but not really getting anywhere.

2x/a < integral of (1/t) dt upper boundary (a+x) lower boundary (a-x) < x(1/(a+x) + 1/(a-x))
