I am trying to prove this as I am practicing for a test but I am pretty much clueless on this problem:(adsbygoogle = window.adsbygoogle || []).push({});

Prove that if ~ is an equivalence relation on a set s and [a] denotes the equivalence class of a in s under ~, then a ~ b if and only if [a] =.

If anyone can give me some points on how to approach or start this problem it would be great. Thanks.
