For let . Apply the CRT to find an integer for . Then for so .
I'm not quite sure how to start on this problem.
Let be mutually prime where .
Let be any integers,then there exists x such that .
Suppose .
Suppose has a solution mod for .
Prove that has a solution mod n.
I don't need to find the solution, just show that one exists.
Do I use the actual solution of , or just the fact that it has a solution. Sorry, I'm just lost on this problem.
