is a solution of 2x + 1 _> 7?

Answer 1

[AI-generated answer — Bot GPT 3.5]

Let's test each number to see if it is a solution to the inequality:

1. For x = 1:
2(1) + 1 = 2 + 1 = 3
3 is not greater than or equal to 7, so 1 is not a solution.

2. For x = 2:
2(2) + 1 = 4 + 1 = 5
5 is not greater than or equal to 7, so 2 is not a solution.

3. For x = 3:
2(3) + 1 = 6 + 1 = 7
7 is equal to 7, so 3 is a solution.

Therefore, the number 3 is the only solution to the inequality 2x + 1 ≥ 7.
