    Assignment:Find the solution set of inequality (x+542)*0.165/68+311/(x+542) ≤1.25 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( x + 542 ) * 0.165 / 68 + 311 / ( x + 542 ) ≤1.25         (1)
        From the definition field of divisor
         x + 542 ≠ 0        (2 )

---

    From inequality(1)：
         x ≤ -542
    From inequality(2)：
         x < -542 或  x ＞ -542

---

    From inequalities (1) and (2)
         x < -542    (3)

---

    The final solution set is :
         x < -542
