    Assignment:Find the solution set of inequality 2(x-1) ≤10-4(x+7.5) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        2 * ( x - 1 ) ≤10 - 4 * ( x + 7.5 )         (1)

---

    From inequality(1)：
         x ≤ -3

---

    The final solution set is :
         x ≤ -3
