[ 1/3Inequality]
    Assignment:Find the solution set of inequality (2a+1)-8 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 2 * a + 1 ) - 8 >0         (1)

---

    From inequality(1)：
         a ＞ 7/2

---

    The final solution set is :
         a ＞ 7/2
[ 2/3Inequality]
    Assignment:Find the solution set of inequality 1+2a+1+2 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 + 2 * a + 1 + 2 >0         (1)

---

    From inequality(1)：
         a ＞ -2

---

    The final solution set is :
         a ＞ -2
[ 3/3Inequality]
    Assignment:Find the solution set of inequality 1-2a-1+2 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 - 2 * a - 1 + 2 >0         (1)

---
