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

---

    From inequality(1)：
        The solution set is empty, that is, within the range of real numbers, the inequality will never be established!
    From inequality(2)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

---

    The final solution set is :
        The solution set is empty,that is, the inequality will never be estatlished within the real number range.
