[ 1/1Inequality]
    Assignment:Find the solution set of inequality （1/（x+4））+1 >-1/（x+6） .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1 / ( x + 4 ) ) + 1 > -1 / ( x + 6 )         (1)
        From the definition field of divisor
         x + 4 ≠ 0        (2 )
        From the definition field of divisor
         x + 6 ≠ 0        (3 )

---

    From inequality(1)：
         x < -7.414214 或  -6 < x < -4.585786 或  x ＞ -4
    From inequality(2)：
         x < -4 或  x ＞ -4
    From inequality(3)：
         x < -6 或  x ＞ -6

---

    From inequalities (1) and (2)
         x < -7.414214 或  -6 < x < -4.585786 或  x ＞ -4    (4)
    From inequalities (3) and (4)
         x < -7.414214 或  -6 < x < -4.585786 或  x ＞ -4    (5)

---

    The final solution set is :
         x < -7.414214 或  -6 < x < -4.585786 或  x ＞ -4
