[ 1/1Inequality]
    Assignment:Find the solution set of inequality 15-9/(6-x) >2.5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        15 - 9 / ( 6 - x ) >2.5         (1)
        From the definition field of divisor
         6 - x ≠ 0        (2 )

---

    From inequality(1)：
         x < 132/25 或  x ＞ 6
    From inequality(2)：
         x < 6 或  x ＞ 6

---

    From inequalities (1) and (2)
         x < 132/25 或  x ＞ 6    (3)

---

    The final solution set is :
         x < 132/25 或  x ＞ 6
