[ 1/1Inequality]
    Assignment:Find the solution set of inequality -1     Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        -1 < x / 10 + 8 / 5 * x         (1)
         x / 10 + 8 / 5 * x <1         (2)

---

    From inequality(1)：
         x ＞ -0.588235
    From inequality(2)：
         x < 0.588235

---

    From inequalities (1) and (2)
         -0.588235 < x < 0.588235     (3)

---

    The final solution set is :
         -0.588235 < x < 0.588235
