    Assignment:Find the solution set of inequality （x-3）/0.5-（10x+40）/0.2 ≤-14 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( x - 3 ) / 0.5 - ( 10 * x + 40 ) / 0.2 ≤ -14         (1)

---

    From inequality(1)：
         x ≥ -4

---

    The final solution set is :
         x ≥ -4
