[ 1/2Inequality]
    Assignment:Find the solution set of inequality x×2800×(565+70x) ≤19600000 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x × 2800 × ( 565 + 70 * x ) ≤19600000         (1)

---

    From inequality(1)：
         -14.819359 ≤ x ≤ 6.74793

---

    The final solution set is :
         -14.819359 ≤ x ≤ 6.74793
