    Assignment:Find the solution set of inequality （118-x）/10 >ln（50/（x-68）） .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 118 - x ) / 10 > ln ( 50 / ( x - 68 ) )         (1)
        From the definition field of divisor
         x - 68 ≠ 0        (2 )
        From the definition field of ln
         50 / ( x - 68 ) > 0        (3 )

---

    From inequality(1)：
         x < 68 或  68.348858 < x < 118
    From inequality(2)：
         x < 68 或  x ＞ 68
    From inequality(3)：
         x ＞ 68

---

    From inequalities (1) and (2)
         x < 68 或  68.348858 < x < 118     (4)
    From inequalities (3) and (4)
         68.348858 < x < 118     (5)

---

    The final solution set is :
         68.348858 < x < 118
