[ 1/1Inequality]
    Assignment:Find the solution set of inequality 2 ≤abs(3-2x) <9 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        2 ≤ abs ( 3 - 2 * x )         (1)
         abs ( 3 - 2 * x ) <9         (2)

---

    From inequality(1)：
         x ≤ 1/2 或  x ≥ 5/2
    From inequality(2)：
         -3 < x < 6

---

    From inequalities (1) and (2)
         -3 < x ≤ 1/2 或  5/2 ≤ x < 6    (3)

---

    The final solution set is :
         -3 < x ≤ 1/2 或  5/2 ≤ x < 6
