Which of the numbers 1, 2, and 3 is a solution of 2x+1≥7 ?

Answer 1

Let's substitute each of the numbers into the inequality and see if it holds true:

1. For x = 1: 2(1) + 1 ≥ 7
2 + 1 ≥ 7
3 ≥ 7 (This is not true)

2. For x = 2: 2(2) + 1 ≥ 7
4 + 1 ≥ 7
5 ≥ 7 (This is not true)

3. For x = 3: 2(3) + 1 ≥ 7
6 + 1 ≥ 7
7 ≥ 7 (This is true)

Therefore, the only solution among the numbers 1, 2, and 3 for the inequality 2x + 1 ≥ 7 is x = 3.
