Logic and Sets - Equality
Hi, bit of help needed please.

Completely stuck on this question, tried for hours working out different possibilities but can’t get anywhere.

"Give an example of a situation where the equality holds, Where X, Y and Z are subsets of the universal set {9, 8, 7, 6}.”

Any help will be much appreciated.

Sorry to tell you but that makes no sense at all.
If we take that quite liberality here is one answer:
$X=\{9,6\},~Y=\{9,6\},~\&~Z=\{9,6\}$.

But that is surely not the meaning.

Please clarify the meaning of the question.

That is all I have been given.

It was part C of a three part question. Part A was about membership tables and part B related to hybrid tables. As far as I can see they don’t hold any relation to the question posted above.
