[ 1/1Inequality]
    Assignment:Find the solution set of inequality -2 <1-1x/5 <3/5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        -2 <1 - 1 * x / 5         (1)
        1 - 1 * x / 5 <3 / 5         (2)

---

    From inequality(1)：
         x < 15
    From inequality(2)：
         x ＞ 2

---

    From inequalities (1) and (2)
         2 < x < 15     (3)

---

    The final solution set is :
         2 < x < 15
