Which inequality is equivalent to −2x + 6 > 10?

  1. Ax < −2
  2. Bx > 2
  3. Cx < 2
  4. Dx > −2
Show answer and rationale

Correct: A. Subtract 6: −2x > 4. Divide by −2 and flip the inequality: x < −2.

  • D — Forgetting to flip the sign gives x > −2.
  • B — Sign error on the constant.
  • C — Sign error on the constant and direction.
