[ 1/2Inequality]
    Assignment:Find the solution set of inequality 3x+4 ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        3 * x + 4 ≥0         (1)

---

    From inequality(1)：
         x ≥ -4/3

---

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

---

    From inequality(1)：
         x ＞ 5/2

---

    The final solution set is :
         x ＞ 5/2
