Question 37
InequalitiesSolve: (y + 2)/4 − (y − 1)/3 > 1.
- A.y < −10
- B.y < −2
- C.y < 2
- D.y < 10
Show the answer and explanation
Answer: B (y < −2)
Explanation
Multiply by 12: 3y + 6 − 4y + 4 > 12, so −y > 2 and y < −2.
Solve: (y + 2)/4 − (y − 1)/3 > 1.
Answer: B (y < −2)
Multiply by 12: 3y + 6 − 4y + 4 > 12, so −y > 2 and y < −2.
