1. Find a solution to each of the following congruences (you might need a calculator): r'...
Discrete structure For each of the following congruences if there is a solution, express the solution in the form x ≡ some_number (mod some_modulus), e.g. x ≡ 6 (mod 9). To standardize answers, some_number should always be a value in the range {0, 1, 2, ..., some_modulus -1}. For example x ≡ 5 (mod 8) is OK but x ≡ 13 (mod 8) is not. If there is no solution say "No solution". You don't have to show work for any of the...
