X*57=0

Solution: x = 0 Reason: By the zero-product property, if x · 57 = 0 and 57 ≠ 0, then x must be 0. Checking: 0 · 57 = 0, which satisfies the equation. Note: In modular arithmetic or other contexts, there could be additional solutions if 57 ≡ 0 (mod m) for the modulus used. But in standard real numbers, x = 0 is the sole solution.
