[ 1/1Inequality]
    Assignment:Find the solution set of inequality 4x-5(2x+3) >5x-1(x-3) <3x-2(x-4) >2x-1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 3 inequalities：
        4 * x - 5 * ( 2 * x + 3 ) >5 * x - 1 * ( x - 3 )         (1)
        5 * x - 1 * ( x - 3 ) <3 * x - 2 * ( x - 4 )         (2)
        3 * x - 2 * ( x - 4 ) >2 * x - 1         (3)

---

    From inequality(1)：
         x < -9/5
    From inequality(2)：
         x < 5/3
    From inequality(3)：
         x < 9

---

    From inequalities (1) and (2)
         x < -9/5    (4)
    From inequalities (3) and (4)
         x < -9/5    (5)

---

    The final solution set is :
         x < -9/5
