How do I find all pairs of (u, v) such that (3n+1)u + (2n+3)v = 7 ?

For any specified 'n' you can pick any 'u' and then solve the equation for 'v' in terms of 'u' and 'n'.

Anyone can do that; I need to find all pairs of (u, v) for which this holds true for all n, such that n is any arbitrary natural number.

If you want this to be true for every n, then the solution must be independent of n. So:
>3n*u+2n*v=0
>u+3v=7

Solving this system yields:
>u=-2
>v=3
