[ 1/1Inequality]
    Assignment:Find the solution set of inequality 850 <= 700-9x <= 862 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        850 <= 700 - 9 * x         (1)
         700 - 9 * x <= 862         (2)

---

    From inequality(1)：
         x ≤ -50/3
    From inequality(2)：
         x ≥ -18

---

    From inequalities (1) and (2)
         -18 ≤ x ≤ -50/3    (3)

---

    The final solution set is :
         -18 ≤ x ≤ -50/3
