[ 1/1Inequality]
    Assignment:Find the solution set of inequality （10000-2400-2500-4000）/x+10000/（x+22.4）+10000/x+10000/x <150 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 10000 - 2400 - 2500 - 4000 ) / x + 10000 / ( x + 22.4 ) + 10000 / x + 10000 / x <150         (1)
        From the definition field of divisor
        x ≠ 0        (2 )
        From the definition field of divisor
         x + 22.4 ≠ 0        (3 )
        From the definition field of divisor
        x ≠ 0        (4 )
        From the definition field of divisor
        x ≠ 0        (5 )

---

    From inequality(1)：
         x < -22.4 或  -15.704576 < x < 0
    From inequality(2)：
         x < 0 或  x ＞ 0
    From inequality(3)：
         x < -112/5 或  x ＞ -112/5
    From inequality(4)：
         x < 0 或  x ＞ 0
    From inequality(5)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         x < -22.4 或  -15.704576 < x < 0     (6)
    From inequalities (3) and (6)
         x < -112/5 或  -15.704576 < x < 0     (7)
    From inequalities (4) and (7)
         x < -112/5 或  -15.704576 < x < 0     (8)
    From inequalities (5) and (8)
         x < -112/5 或  -15.704576 < x < 0     (9)

---

    The final solution set is :
         x < -112/5 或  -15.704576 < x < 0
