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

---

    From inequality(1)：
         x ＞ -2

---

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

---

    From inequality(1)：
         x < 3

---

    The final solution set is :
         x < 3
