Algebra practice question

Which of the following values of x satisfies both 2x − 3 > 5 and 10 − x ≥ 3?

  1. A. 6Correct
  2. B. 4
  3. C. 8
  4. 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.
