    Assignment:Find the solution set of inequality 13 <25x <15 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        13 <25 * x         (1)
        25 * x <15         (2)

---

    From inequality(1)：
         x ＞ 13/25
    From inequality(2)：
         x < 3/5

---

    From inequalities (1) and (2)
         13/25 < x < 3/5     (3)

---

    The final solution set is :
         13/25 < x < 3/5
