[ 1/1Inequality]
    Assignment:Find the solution set of inequality 10000/x+10000/(x+8)*0+10000/(x+16)+10000/(x+24)*7 <= 450 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        10000 / x + 10000 / ( x + 8 ) * 0 + 10000 / ( x + 16 ) + 10000 / ( x + 24 ) * 7 <= 450         (1)
        From the definition field of divisor
        x ≠ 0        (2 )
        From the definition field of divisor
         x + 8 ≠ 0        (3 )
        From the definition field of divisor
         x + 16 ≠ 0        (4 )
        From the definition field of divisor
         x + 24 ≠ 0        (5 )

    From inequality(1)：
         x ≤ -24 或  -17.098035 ≤ x ≤ -16 或  -2.774644 ≤ x ≤ 0 或  x ≥ 179.872679
    From inequality(2)：
         x < 0 或  x ＞ 0
    From inequality(3)：
         x < -8 或  x ＞ -8
    From inequality(4)：
         x < -16 或  x ＞ -16
    From inequality(5)：
         x < -24 或  x ＞ -24

---

    From inequalities (1) and (2)
         x ≤ -24 或  -17.098035 ≤ x ≤ -16 或  -2.774644 ≤ x < 0 或  x ≥ 179.872679    (6)
    From inequalities (3) and (6)
         x ≤ -24 或  -17.098035 ≤ x ≤ -16 或  -2.774644 ≤ x < 0 或  x ≥ 179.872679    (7)
    From inequalities (4) and (7)
         x ≤ -24 或  -17.098035 ≤ x < -16 或  -2.774644 ≤ x < 0 或  x ≥ 179.872679    (8)
    From inequalities (5) and (8)
         x < -24 或  -17.098035 ≤ x < -16 或  -2.774644 ≤ x < 0 或  x ≥ 179.872679    (9)

---

    The final solution set is :
         x < -24 或  -17.098035 ≤ x < -16 或  -2.774644 ≤ x < 0 或  x ≥ 179.872679
