    Assignment:Find the solution set of inequality 93400/（X+1401）-93400/（x+1601） <40 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        93400 / ( X + 1401 ) - 93400 / ( X + 1601 ) <40         (1)
        From the definition field of divisor
         x + 1401 ≠ 0        (2 )
        From the definition field of divisor
         x + 1601 ≠ 0        (3 )

---

    From inequality(1)：
         X ＞ -810.348134
    From inequality(2)：
         X < -1401 或  X ＞ -1401
    From inequality(3)：
         X < -1601 或  X ＞ -1601

---

    From inequalities (1) and (2)
         X ＞ -810.348134    (4)
    From inequalities (3) and (4)
         X ＞ -810.348134    (5)

---

    The final solution set is :
         X ＞ -810.348134
