[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1/（1-x）+1/（1-1.1x） >26 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 / ( 1 - x ) + 1 / ( 1 - 1.1 * x ) >26         (1)
        From the definition field of divisor
         1 - x ≠ 0        (2 )
        From the definition field of divisor
         1 - 1.1 * x ≠ 0        (3 )

---

    From inequality(1)：
         0.860779 < x < 0.909091
    From inequality(2)：
         x < 1 或  x ＞ 1
    From inequality(3)：
         x < 10/11 或  x ＞ 10/11

---

    From inequalities (1) and (2)
         0.860779 < x < 0.909091     (4)
    From inequalities (3) and (4)
         0.860779 < x < 10/11     (5)

---

    The final solution set is :
         0.860779 < x < 10/11
