You're right, this is equivalent 3×X=15 and X!=5 problem.
This is an example from a hungarian middle school mathematics book.
The reason of the term 1/(X-5) to check the student can to reduce the set of the real numbers (5 is not belongs to \( \Bbb R\) )

I just use it to test CAS systems - and all of them fails.

I really do not understand why do you do not see, this is a really big problem. How you can trust a system, if that system cannot solve this simple, midschool straigh example.
