    Assignment:Find the solution set of inequality 0.7(x+9)-6.5(2x-1) <= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        0.7 * ( x + 9 ) - 6.5 * ( 2 * x - 1 ) <= 0         (1)

---

    From inequality(1)：
         x ≥ 1.04065

---

    The final solution set is :
         x ≥ 1.04065
