Linear Congruence Equation -- from Wolfram MathWorld

Web$\begingroup$ For Diophantine equations coming from curves, the Hasse-Weil bound shows that you can solve your Diophantine equation mod p for any sufficiently large prime p, and for higher dimensional varieties I suspect one can use the Weil conjectures to get a similar result. Furthermore, if the equation is solvable mod p, then usually Hensel's lemma allows … WebDec 5, 2024 · x = (s - kh) / (kr) mod q, if gcd (k*r, q) == 1. (1/kr) is the modular inverse of k*r. It basically the same answer you'd get if you were solving over the reals, except division is a different algorithm and "can't divide by zero" is replaced by gcd (k*r, q) == 1. This doesn't seem to work. I also arrived at this equation earlier and if I use it ...
