[ 1/1Inequality]
    Assignment:Find the solution set of inequality -9/x+3*ln（3/x） >-6 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -9 / x + 3 * ln ( 3 / x ) > -6         (1)
        From the definition field of divisor
        x ≠ 0        (2 )
        From the definition field of divisor
        x ≠ 0        (3 )
        From the definition field of ln
         3 / x > 0        (4 )

---

    From inequality(1)：
         0.953533 < x < 18.916186
    From inequality(2)：
         x < 0 或  x ＞ 0
    From inequality(3)：
         x < 0 或  x ＞ 0
    From inequality(4)：
         x ＞ 0

---

    From inequalities (1) and (2)
         0.953533 < x < 18.916186     (5)
    From inequalities (3) and (5)
         0.953533 < x < 18.916186     (6)
    From inequalities (4) and (6)
         0.953533 < x < 18.916186     (7)

---

    The final solution set is :
         0.953533 < x < 18.916186
