Determine whether each of the following statements is True or False. If True, write a proof. If False, exhibit a counterexample.

1) If m, n are arbitrary positive integers, then any system of form

x ≡ a (mod m)

x ≡ b (mod n)

has a solution.



2) If m, n are arbitrary positive integers and the system

x ≡ a (mod m)

x ≡ b (mod n)

    has a solution, then the solution is unique modulo mn.
