[ 1/1Inequality]
    Assignment:Find the solution set of inequality (10x)/(5x+2) >8 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 10 * x ) / ( 5 * x + 2 ) >8         (1)
        From the definition field of divisor
         5 * x + 2 ≠ 0        (2 )

---

    From inequality(1)：
         -8/15 < x < -0.4
    From inequality(2)：
         x < -2/5 或  x ＞ -2/5

---

    From inequalities (1) and (2)
         -8/15 < x < -0.4     (3)

---

    The final solution set is :
         -8/15 < x < -0.4
