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 ... WebEvery modulus is a non-negative number and if two non-negative numbers add up to get zero then individual numbers itself equal to zero simultaneously. x 2 – 5x + 6 = 0 for x = 2 or 3. x 2 – 8x + 12 = 0 for x = 2 or 6. Both the equations are zero at x = 2. So, x = 2 is the only solution for this equation. Example 3: Solve for x, x – 1 ...
