[ 1/2Inequality]
    Assignment:Find the solution set of inequality abs(1.5*x) <0.75 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         abs ( 1.5 * x ) <0.75         (1)

---

    From inequality(1)：
         -1/2 < x < 1/2

---

    The final solution set is :
         -1/2 < x < 1/2
[ 2/2Inequality]
    Assignment:Find the solution set of inequality abs(-0.75-1.5*x) <0.75 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         abs ( -0.75 - 1.5 * x ) <0.75         (1)

---

    From inequality(1)：
         -1 < x < 0

---

    The final solution set is :
         -1 < x < 0
