    Assignment:Find the solution set of inequality ln(6-23.2x)-ln(6+23.2x)+7.7x >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ln ( 6 - 23.2 * x ) - ln ( 6 + 23.2 * x ) + 7.7 * x >0         (1)
        From the definition field of ln
         6 - 23.2 * x > 0        (2 )
        From the definition field of ln
         6 + 23.2 * x > 0        (3 )

---

    From inequality(1)：
         x < 0
    From inequality(2)：
         x < 0.258621
    From inequality(3)：
         x ＞ -0.258621

---

    From inequalities (1) and (2)
         x < 0    (4)
    From inequalities (3) and (4)
         -0.258621 < x < 0     (5)

---

    The final solution set is :
         -0.258621 < x < 0
