    Assignment:Find the solution set of inequality 45 <3x+3（x÷3） >50 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        45 <3 * x + 3 * ( x ÷ 3 )         (1)
        3 * x + 3 * ( x ÷ 3 ) >50         (2)

---

    From inequality(1)：
         x ＞ 45/4
    From inequality(2)：
         x ＞ 25/2

---

    From inequalities (1) and (2)
         x ＞ 25/2    (3)

---

    The final solution set is :
         x ＞ 25/2
