    Assignment:Find the solution set of inequality 14 <18x <16 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        14 <18 * x         (1)
        18 * x <16         (2)

---

    From inequality(1)：
         x ＞ 7/9
    From inequality(2)：
         x < 8/9

---

    From inequalities (1) and (2)
         7/9 < x < 8/9     (3)

---

    The final solution set is :
         7/9 < x < 8/9
