determine if the following congruence has an integer solution: 5x + 4 congruent to 5 (mod 100)
The only way I could envision this working is by trying all of the remainder values of 100, but I don't think that is the way to go considering there is so many. I tried to figure out an equivalency for 5 [itex]\equiv[/itex] x (mod 100) but that got me nowhere as well.
What's the simple property I'm probably missing here?
