SUMMARY
The congruence equation x^11 + 3x^10 + 5x ≡ 2 (mod 11) has solutions based on the condition that gcd(a, m) must divide c. In this case, since 11 divides the expression x^11 + 3x^10 + 5x - 2, and testing x = 1 yields gcd(11, 9) = 1, which divides 2, a solution exists. The approach to find specific solutions involves checking integers from 1 to 10 to identify which values satisfy the congruence.
