(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Prove that when R and S are equivalence relations, then SR is

equivalance relation when SR=RS.

2. Relevant equations

3. The attempt at a solution

I want to know what sets should i take for the relations ?

is it ok when i take R a a subset of X x Y and S as a subset of Y

and Z or should i take it some other way?

then SR is a subset of X x Z ? am i moving right?

also when tring to solve this problem I found that x has to be equal

to y when SR = RS..

Thank you!
