1. The problem statement, all variables and given/known data
Let a,b be integers where a doesn't =0. Prove that if a divides b, and b divides a, then a=b or a=b 3. The attempt at a solution I started out with b=aj and a=bk, where j,k are integers. Don't quite know how to proceed

Substitute the expression for a or b into the other equation. What do you get?
