[ 1/1Inequality]
    Assignment:Find the solution set of inequality 50 ≤X ≤86 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        50 ≤ x         (1)
         x ≤86         (2)

---

    From inequality(1)：
         x ≥ 50
    From inequality(2)：
         x ≤ 86

---

    From inequalities (1) and (2)
         50 ≤ x ≤ 86    (3)

---

    The final solution set is :
         50 ≤ x ≤ 86
