[ 1/1Inequality]
    Assignment:Find the solution set of inequality (x+68)/(x+8) ≥5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( x + 68 ) / ( x + 8 ) ≥5         (1)
        From the definition field of divisor
         x + 8 ≠ 0        (2 )

---

    From inequality(1)：
         -8 ≤ x ≤ 7
    From inequality(2)：
         x < -8 或  x ＞ -8

---

    From inequalities (1) and (2)
         -8 < x ≤ 7     (3)

---

    The final solution set is :
         -8 < x ≤ 7
