[ 1/1Inequality]
    Assignment:Find the solution set of inequality 20/(20x+2)-19/(19x+1.4) >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        20 / ( 20 * x + 2 ) - 19 / ( 19 * x + 1.4 ) >0         (1)
        From the definition field of divisor
         20 * x + 2 ≠ 0        (2 )
        From the definition field of divisor
         19 * x + 1.4 ≠ 0        (3 )

---

    From inequality(1)：
        The solution set is empty, that is, within the range of real numbers, the inequality will never be established!
    From inequality(2)：
         x < -1/10 或  x ＞ -1/10
    From inequality(3)：
         x < -0.073684 或  x ＞ -0.073684

---

    The final solution set is :
        The solution set is empty,that is, the inequality will never be estatlished within the real number range.
