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

---

    From inequality(1)：
         x ≤ 2

---

    The final solution set is :
         x ≤ 2
[ 2/2Inequality]
    Assignment:Find the solution set of inequality (x+3)/2 >1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( x + 3 ) / 2 >1         (1)

---

    From inequality(1)：
         x ＞ -1

---

    The final solution set is :
         x ＞ -1
