What does "Solve $ax \equiv b \pmod{337}$ for $x$" mean? I have a general question about modular equations:
Let's say I have this simple equation:
$$ax\equiv b \pmod{337}$$
I need to solve the equation.
What does "solve the equation" mean? There are an infinite number of $x$'s that will be correct.
Does $x$ need to be integer?
Thanks very much in advance,
Yaron.

Typically this question means to find all the integer $x$ in the interval $[0,336]$ satisfying the equation.
