    Assignment:Find the solution set of inequality 3 <11.7×（8-x)÷26.6x <6 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        3 <11.7 × ( 8 - x ) ÷ 26.6 * x         (1)
        11.7 × ( 8 - x ) ÷ 26.6 * x <6         (2)

---

    From inequality(1)：
         0.970233 < x < 7.029767
    From inequality(2)：
         x < 2.464105 或  x ＞ 5.535895

---

    From inequalities (1) and (2)
         0.970233 < x < 2.464105 或  5.535895 < x < 7.029767     (3)

---

    The final solution set is :
         0.970233 < x < 2.464105 或  5.535895 < x < 7.029767
