1. The problem statement, all variables and given/known data Find the integer y with both 0 < y < 144 and 35y = 42(mod 144) 2. Relevant equations 3. The attempt at a solution Can someone help me get started on this one? I understand that I can reduce it to 5y = 6(mod 144), and then to 5y = 6 + 144... but I'm not sure what to do with that. I mean, can I just do 5y = 150 and then y = 30?
