Homework Help: First x which satisfies x-3>0

  1. Feb 23, 2012 #1
    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?
