Which of the following describes all values of x that satisfy 3 − 2x > 4x + 15?
- A. x < −2Correct
- B. x > −2
- C. x < 2
- D. x > −3
Answer: A. x < −2
3 − 15 > 6x gives −12 > 6x, so x < −2.
Why the other answers are wrong
- B. x > −2
- The inequality direction is wrong.
- C. x < 2
- The sign of 2 is wrong.
- D. x > −3
