    Assignment:Find the solution set of inequality -3 <2÷(3x-1) <2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        -3 <2 ÷ ( 3 * x - 1 )         (1)
        2 ÷ ( 3 * x - 1 ) <2         (2)

---

    From inequality(1)：
         x < 1/9 或  x ＞ 0.333333
    From inequality(2)：
         x < 0.333333 或  x ＞ 2/3

---

    From inequalities (1) and (2)
         x < 1/9 或  x ＞ 2/3    (3)

---

    The final solution set is :
         x < 1/9 或  x ＞ 2/3
