[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1-2x ≥0 ≥x+2 >2x-1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 3 inequalities：
        1 - 2 * x ≥0         (1)
        0 ≥ x + 2         (2)
         x + 2 >2 * x - 1         (3)

---

    From inequality(1)：
         x ≤ 1/2
    From inequality(2)：
         x ≤ -2
    From inequality(3)：
         x < 3

---

    From inequalities (1) and (2)
         x ≤ -2    (4)
    From inequalities (3) and (4)
         x ≤ -2    (5)

---

    The final solution set is :
         x ≤ -2
