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

---

    From inequality(1)：
         -7 < x < 5/3

---

    The final solution set is :
         -7 < x < 5/3
