    Assignment:Find the solution set of inequality 10000/X+2900/（X+21.4） ≤63.131313 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        10000 / X + 2900 / ( X + 21.4 ) ≤63.131313         (1)
        From the definition field of divisor
        x ≠ 0        (2 )
        From the definition field of divisor
         x + 21.4 ≠ 0        (3 )

---

    From inequality(1)：
         X ≤ -21.4 或  -16.957804 ≤ X ≤ 0 或  X ≥ 199.893805
    From inequality(2)：
         X < 0 或  X ＞ 0
    From inequality(3)：
         X < -107/5 或  X ＞ -107/5

---

    From inequalities (1) and (2)
         X ≤ -21.4 或  -16.957804 ≤ X < 0 或  X ≥ 199.893805    (4)
    From inequalities (3) and (4)
         X < -107/5 或  -16.957804 ≤ X < 0 或  X ≥ 199.893805    (5)

---

    The final solution set is :
         X < -107/5 或  -16.957804 ≤ X < 0 或  X ≥ 199.893805
