[ 1/1Inequality]
    Assignment:Find the solution set of inequality (（53x+200）-(x-1)*20)/（x+10） >50 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( ( 53 * x + 200 ) - ( x - 1 ) * 20 ) / ( x + 10 ) >50         (1)
        From the definition field of divisor
         x + 10 ≠ 0        (2 )

---

    From inequality(1)：
         -16.470588 < x < -10
    From inequality(2)：
         x < -10 或  x ＞ -10

---

    From inequalities (1) and (2)
         -16.470588 < x < -10     (3)

---

    The final solution set is :
         -16.470588 < x < -10
