[ 1/1Inequality]
    Assignment:Find the solution set of inequality 3 <= (2x-1)/3 <4 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        3 <= ( 2 * x - 1 ) / 3         (1)
         ( 2 * x - 1 ) / 3 <4         (2)

---

    From inequality(1)：
         x ≥ 5
    From inequality(2)：
         x < 13/2

---

    From inequalities (1) and (2)
         5 ≤ x < 13/2    (3)

---

    The final solution set is :
         5 ≤ x < 13/2
