Correct me if I'm wrong, but aren't both of these technically the same? I don't understand how one could be wrong and the other right if they both apply to x.

x >= 2 solves both equations so that would be 'AND'

x > 1 could also be anything between 1 and 2, such as 1.1 or 1.55. which only solves 2x+9>11. So 'OR' is used.

You are not restricted to Integers only, unless the problem states that.
