[ 1/1Inequality]
    Assignment:Find the solution set of inequality -20 <(2x*2)-x-3 <25 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        -20 < ( 2 * x * 2 ) - x - 3         (1)
         ( 2 * x * 2 ) - x - 3 <25         (2)

---

    From inequality(1)：
         x ＞ -17/3
    From inequality(2)：
         x < 28/3

---

    From inequalities (1) and (2)
         -17/3 < x < 28/3     (3)

---

    The final solution set is :
         -17/3 < x < 28/3
