Actually, based on the work on Hilbert's 10th problem it's a routine 
exercise for a student. In fact it's just a matter of inserting a suitable 
(very large) integer for a parameter in a universal equation.

It's clear that Professor Kanovei and I use the term "mathematical meaning" 
quite differently. I can't imagine what would be clearer than an assertion 
that a particular explicitly displayed system of polynomial equation has a 
solution in natural numbers.
