    Assignment:Find the solution set of inequality 23 <56x+3 <255 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        23 <56 * x + 3         (1)
        56 * x + 3 <255         (2)

---

    From inequality(1)：
         x ＞ 0.357143
    From inequality(2)：
         x < 9/2

---

    From inequalities (1) and (2)
         0.357143 < x < 9/2     (3)

---

    The final solution set is :
         0.357143 < x < 9/2
