    Assignment:Find the solution set of inequality -7小于或等于x+5小于或等于7 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        -7 ≤ x + 5         (1)
         x + 5 ≤7         (2)

---

    From inequality(1)：
         x ≥ -12
    From inequality(2)：
         x ≤ 2

---

    From inequalities (1) and (2)
         -12 ≤ x ≤ 2    (3)

---

    The final solution set is :
         -12 ≤ x ≤ 2
