Let's substitute each number into the inequality and check if it holds true:
1. For x = 1:
2(1) + 1 = 3, which is not greater than or equal to 7. Therefore, 1 is not a solution.
2. For x = 2:
2(2) + 1 = 5, which is not greater than or equal to 7. Therefore, 2 is not a solution.
3. For x = 3:
2(3) + 1 = 7, which is equal to 7. Therefore, 3 is a solution.
Based on the substitution, only x = 3 is a solution to the inequality 2x + 1 ≥ 7.
1. For x = 1:
2(1) + 1 = 3, which is not greater than or equal to 7. Therefore, 1 is not a solution.
2. For x = 2:
