[ 2/2Inequality]
    Assignment:Find the solution set of inequality 3x-4 <= 11-2x .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        3 * x - 4 <= 11 - 2 * x         (1)

---

    From inequality(1)：
         x ≤ 3

---

    The final solution set is :
         x ≤ 3
