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

---

    From inequality(1)：
         x ＞ -3/2

---

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

---

    From inequality(1)：
         x < 3

---

    The final solution set is :
         x < 3
