[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1 ≤1-2a ≤5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        1 ≤1 - 2 * a         (1)
        1 - 2 * a ≤5         (2)

---

    From inequality(1)：
         a ≤ 0
    From inequality(2)：
         a ≥ -2

---

    From inequalities (1) and (2)
         -2 ≤ a ≤ 0    (3)

---

    The final solution set is :
         -2 ≤ a ≤ 0
