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

Answer 1

To determine if a number is a solution to the inequality 2x + 1 ≥ 7, we need to substitute the number into the inequality and see if it holds true.

Let's start by checking if 1 is a solution:
2(1) + 1 ≥ 7
2 + 1 ≥ 7
3 ≥ 7
This is not true, so 1 is not a solution to the inequality.

Next, let's check if 2 is a solution:
2(2) + 1 ≥ 7
4 + 1 ≥ 7
5 ≥ 7
This is also not true, so 2 is not a solution to the inequality.

Lastly, let's check if 3 is a solution:
2(3) + 1 ≥ 7
6 + 1 ≥ 7
7 ≥ 7
This is true, so 3 is a solution to the inequality.

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

Answer 2

so x 3 or just 3

Answer 3

Sorry for the confusion. In this case, x represents a variable while 3 is the solution to the inequality. Therefore, the solution is x = 3.
