How do I solve those problems?
Like,
Find some x such that x[tex]\equiv[/tex]8 mod (18)
Find the inverse of 12 modulo 41
Solve 2x=7 mod (13)
I know it's easy, but I don't get it.
That's the explanation in the book. I'm not getting it. Can somebody please explain this modular arithmetic to me?

Let a and be be integers, and let m be a positive integer. Then a [tex]\equiv[/tex] b ( mod m) if and only if a mod m = b mod m
