Which of the following inequalities has no solution?
- A. x + 3 > x + 5Correct
- B. 2x > x
- C. x < 5
- D. 3x ≥ 3x
Answer: A. x + 3 > x + 5
x + 3 > x + 5 simplifies to 3 > 5, which is false for every x.
Why the other answers are wrong
- B. 2x > x
- 2x > x holds for every positive x.
- C. x < 5
- Any number less than 5 works.
- D. 3x ≥ 3x
- 3x ≥ 3x is true for every x.
