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

---

    From inequality(1)：
         -4 < x < 2
    From inequality(2)：
         x < -4 或  x ＞ -4

---

    From inequalities (1) and (2)
         -4 < x < 2     (3)

---

    The final solution set is :
         -4 < x < 2
