    Assignment:Find the solution set of inequality 1.5*(20-x)+1.2(30+1.5x) ≤69 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1.5 * ( 20 - x ) + 1.2 * ( 30 + 1.5 * x ) ≤69         (1)

---

    From inequality(1)：
         x ≤ 10

---

    The final solution set is :
         x ≤ 10
