    Assignment:Find the solution set of inequality x-3 <2x+5 <7 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
         x - 3 <2 * x + 5         (1)
        2 * x + 5 <7         (2)

---

    From inequality(1)：
         x ＞ -8
    From inequality(2)：
         x < 1

---

    From inequalities (1) and (2)
         -8 < x < 1     (3)

---

    The final solution set is :
         -8 < x < 1
