[ 1/1Inequality]
    Assignment:Find the solution set of inequality (5x+39)/(x+7) ≤3 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 5 * x + 39 ) / ( x + 7 ) ≤3         (1)
        From the definition field of divisor
         x + 7 ≠ 0        (2 )

---

    From inequality(1)：
         -9 ≤ x ≤ -7
    From inequality(2)：
         x < -7 或  x ＞ -7

---

    From inequalities (1) and (2)
         -9 ≤ x < -7    (3)

---

    The final solution set is :
         -9 ≤ x < -7
