    Assignment:Find the solution set of inequality 308*a/(a+88) >220 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        308 * a / ( a + 88 ) >220         (1)
        From the definition field of divisor
         x + 88 ≠ 0        (2 )

---

    From inequality(1)：
         a < -88
    From inequality(2)：
         a < -88 或  a ＞ -88

---

    From inequalities (1) and (2)
         a < -88    (3)

---

    The final solution set is :
         a < -88
