    Assignment:Find the solution set of inequality 163020/475-163020/（475+x） <5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        163020 / 475 - 163020 / ( 475 + x ) <5         (1)
        From the definition field of divisor
         475 + x ≠ 0        (2 )

---

    From inequality(1)：
         x < 7.022472
    From inequality(2)：
         x < -475 或  x ＞ -475

---

    From inequalities (1) and (2)
         x < -475 或  -475 < x < 7.022472     (3)

---

    The final solution set is :
         x < -475 或  -475 < x < 7.022472
