Which of the numbers 1,2 and 3 is a solution of 2x+1>7 where the > is underscored

Answer 1

To determine which numbers are solutions of the inequality 2x + 1 > 7, we need to substitute each number into the inequality and see if it holds true.

1. For x = 1:
2(1) + 1 > 7
2 + 1 > 7
3 > 7
This is false, so 1 is not a solution.

2. For x = 2:
2(2) + 1 > 7
4 + 1 > 7
5 > 7
This is false, so 2 is not a solution.

3. For x = 3:
2(3) + 1 > 7
6 + 1 > 7
7 > 7
This is false, so 3 is not a solution.

Therefore, none of the numbers 1, 2, or 3 is a solution of the inequality 2x + 1 > 7.
