First x which satisfies x-3>0

1. The problem statement, all variables and given/known data
What's the first x value which satisfies x-3>0?


2. Relevant equations
x-3>0

3. The attempt at a solution
3 + an infinitesimal number would satisfy this, but I have no idea how to write it down in a proper algebraic form.

What is x? Is it an integer, a rational, a real?
