[ 1/1Inequality]
    Assignment:Find the solution set of inequality -5 <(2x+1)/(2x-1) <5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        -5 < ( 2 * x + 1 ) / ( 2 * x - 1 )         (1)
         ( 2 * x + 1 ) / ( 2 * x - 1 ) <5         (2)
        From the definition field of divisor
         2 * x - 1 ≠ 0        (3 )

---

    From inequality(1)：
         x < 1/3 或  x ＞ 0.5
    From inequality(2)：
         x < 0.5 或  x ＞ 3/4
    From inequality(3)：
         x < 1/2 或  x ＞ 1/2

---

    From inequalities (1) and (2)
         x < 1/3 或  x ＞ 3/4    (4)
    From inequalities (3) and (4)
         x < 1/3 或  x ＞ 3/4    (5)

---

    The final solution set is :
         x < 1/3 或  x ＞ 3/4
