Algebra practice question
Which of the following values of x satisfies both 2x − 3 > 5 and 10 − x ≥ 3?
- A. 6Correct
- B. 4
- C. 8
- D. 3
Answer: A. 6
2x − 3 > 5 gives x > 4, and 10 − x ≥ 3 gives x ≤ 7. Only 6 lies in 4 < x ≤ 7.
Why the other answers are wrong
- B. 4
- 4 makes 2x − 3 = 5, which is not greater than 5.
- C. 8
- 8 gives 10 − 8 = 2, which is less than 3.
- D. 3
- 3 fails the first inequality: 2(3) − 3 = 3.
