[ 1/1Inequality]
    Assignment:Find the solution set of inequality 2 ≤4-0.5x <4 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        2 ≤4 - 0.5 * x         (1)
        4 - 0.5 * x <4         (2)

---

    From inequality(1)：
         x ≤ 4
    From inequality(2)：
         x ＞ 0

---

    From inequalities (1) and (2)
         0 < x ≤ 4     (3)

---

    The final solution set is :
         0 < x ≤ 4
