    Assignment:Find the solution set of inequality 1.0×2159.4×1000000 ≤19.1×2000×(2140-x/2) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1.0 × 2159.4 × 1000000 ≤19.1 × 2000 × ( 2140 - x / 2 )         (1)

---

    From inequality(1)：
        The solution set is empty, that is, within the range of real numbers, the inequality will never be established!

---

    The final solution set is :
        The solution set is empty,that is, the inequality will never be estatlished within the real number range.
