"Nowadays, people approach mathematics in a way that deviates so much from the original point that it's hard to even call it mathematics. Mathematics isn't just solving equations, graphing functions, or finding derivatives; the entire point of mathematics is to reveal deeper understandings of our observable universe, which is why finding x is rarely productive. Without a deeper meaning, at the end of the day, finding a polynomial doesn't reveal anything new because somebody else has solved said polynomial before. In order to truly find x, one must find themselves, or at the very least find what type of person they are. Lazy people would likely try to take the easy way out, leaving x as undefined or setting x equal to 0 and claiming they're finished. While they aren't lying- they have found x after all- they are doing themselves a disservice by not going a deeper level. Another approach would be to find an equation to plug x into, but that isn't much better. Setting x equal to 2 – 1 or – e^(i*π) will give you the same answer, just one looks a lot more showy in presentation, so having x equal to a constant is still insignificant. Considering the universe is infinite, any number would seem small in the grand scheme of things. 100 seems like a big number compared to 1, and a million seems even greater compared to both, but neither are big compared to the total number of stars in the universe, the grains of sands of every desert and beach, etc.. When considering that then, some people would say that x equals infinity. But really, anything can be “infinite” so that answer isn't particularly profound either. The comedic and the religious could both argue that the answer would be Jesus since “Jesus is always the answer,” which would certainly be accepted in some circles. But finding x was never about what x is equal to anyway, finding x says more about who you are as a person and how you apply yourself. If done properly, finding x can reveal new information about yourself, others, the universe, and anything you can possibly want an answer to. I think the noted academic scholar DMX said it best in his acclaimed thesis “x gon' give it to ya.” "
