To test which numbers are solutions, we can substitute them into the inequality and see if it is true.
If x = 1:
2(1) + 1 ≥ 7
2 + 1 ≥ 7
3 is not greater than or equal to 7, so 1 is not a solution.
If x = 2:
2(2) + 1 ≥ 7
4 + 1 ≥ 7
5 is not greater than or equal to 7, so 2 is not a solution.
If x = 3:
2(3) + 1 ≥ 7
6 + 1 ≥ 7
7 is greater than or equal to 7, so 3 is a solution.
Therefore, the answer is 3.
