    Assignment:Find the solution set of inequality (278-x)/(45-x) >8 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 278 - x ) / ( 45 - x ) >8         (1)
        From the definition field of divisor
         45 - x ≠ 0        (2 )

---

    From inequality(1)：
         82/7 < x < 45
    From inequality(2)：
         x < 45 或  x ＞ 45

---

    From inequalities (1) and (2)
         82/7 < x < 45     (3)

---

    The final solution set is :
         82/7 < x < 45
