I am attempting to write code that can "solve-for-x" on any mathematical expression ranging from $x - 2 = 0 $ $ $ to $ $ $ 97x^{51} - 60^x = 1$, and all the way through expressions like $W=\int_{k<\wedge}[Dg][Da][D\psi][D\phi]\exp\left\{i\int{d^4x\sqrt{-g}\left[\frac{m^2_p}{2}R-\frac{1}{4}F^a_{\mu\nu}F^{a\mu\upsilon}+i\psi^i\gamma^{\mu}D_\mu\psi^i+\left(\psi^i_LV_{ij}\phi\psi_R^j + h.c.\right)-|D_\mu\phi|^2-V(\phi)\right]}\right\}$ and beyond (P.S. I just looked up big equation to exemplify my goal. I don't understand it's purpose, so please just don't ask about it).
What I am looking for is a webpage the contains a very very long list of all properties of all operators (including modulo and bitwise), and all techniques used to "solve for x" (or that are related to "solve for x") in any form. Preferably, I would prefer the list to have been created within the past 2 years, and contains every extrapolation (no matter how extraneous) on it. The reason for why I am looking for a list is so I can go through linearly, so that I don't miss anything.
