[ 1/2Inequality]
    Assignment:Find the solution set of inequality 3z-8-5(z-1) >= 1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        3 * z - 8 - 5 * ( z - 1 ) >= 1         (1)

---

    From inequality(1)：
         z ≤ -2

---

    The final solution set is :
         z ≤ -2
[ 2/2Inequality]
    Assignment:Find the solution set of inequality 3z-8-5(z-1 ) <5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        3 * z - 8 - 5 * ( z - 1 ) <5         (1)

---

    From inequality(1)：
         z ＞ -4

---

    The final solution set is :
         z ＞ -4
