[ 1/1Inequality]
    Assignment:Find the solution set of inequality 4 <= y+2 <= -3(y-2)+24 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        4 <= y + 2         (1)
         y + 2 <= -3 * ( y - 2 ) + 24         (2)

---

    From inequality(1)：
         y ≥ 2
    From inequality(2)：
         y ≤ 7

---

    From inequalities (1) and (2)
         2 ≤ y ≤ 7    (3)

---

    The final solution set is :
         2 ≤ y ≤ 7
