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:

$\displaystyle X=\{9,6\},~Y=\{9,6\},~\&~Z=\{9,6\}$.

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.

In that case, the best you can do is post the entire question exactly as written and hope that someone knows what is going there.
