    Assignment:Find the solution set of inequality 90 <11y-2 <100 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        90 <11 * y - 2         (1)
        11 * y - 2 <100         (2)

---

    From inequality(1)：
         y ＞ 92/11
    From inequality(2)：
         y < 102/11

---

    From inequalities (1) and (2)
         92/11 < y < 102/11     (3)

---

    The final solution set is :
         92/11 < y < 102/11
