[ 1/1Inequality]
    Assignment:Find the solution set of inequality (2522+x)/(2522+3103+x) >= 0.45 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 2522 + x ) / ( 2522 + 3103 + x ) >= 0.45         (1)
        From the definition field of divisor
         2522 + 3103 + x ≠ 0        (2 )

---

    From inequality(1)：
         x ≥ 185/11
    From inequality(2)：
         x < -5625 或  x ＞ -5625

---

    From inequalities (1) and (2)
         x ≥ 185/11    (3)

---

    The final solution set is :
         x ≥ 185/11
