[ 1/1Inequality]
    Assignment:Find the solution set of inequality 2.5/(1+x)*3+1.5/(1+x) >8 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        2.5 / ( 1 + x ) * 3 + 1.5 / ( 1 + x ) >8         (1)
        From the definition field of divisor
         1 + x ≠ 0        (2 )
        From the definition field of divisor
         1 + x ≠ 0        (3 )

---

    From inequality(1)：
         -1 < x < 1/8
    From inequality(2)：
         x < -1 或  x ＞ -1
    From inequality(3)：
         x < -1 或  x ＞ -1

---

    From inequalities (1) and (2)
         -1 < x < 1/8     (4)
    From inequalities (3) and (4)
         -1 < x < 1/8     (5)

---

    The final solution set is :
         -1 < x < 1/8
