[ 1/1Inequality]
    Assignment:Find the solution set of inequality -1 <2+x ≤2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        -1 <2 + x         (1)
        2 + x ≤2         (2)

---

    From inequality(1)：
         x ＞ -3
    From inequality(2)：
         x ≤ 0

---

    From inequalities (1) and (2)
         -3 < x ≤ 0     (3)

---

    The final solution set is :
         -3 < x ≤ 0
