[ 1/1Inequality]
    Assignment:Find the solution set of inequality 4(3y-1)+3(2y+9) <= 3y-7 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        4 * ( 3 * y - 1 ) + 3 * ( 2 * y + 9 ) <= 3 * y - 7         (1)

---

    From inequality(1)：
         y ≤ -2

---

    The final solution set is :
         y ≤ -2
