[ 1/1Inequality]
    Assignment:Find the solution set of inequality (47755*427+49000*X)/48228 >= 427+X <= 20000 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
         ( 47755 * 427 + 49000 * X ) / 48228 >= 427 + X         (1)
         427 + X <= 20000         (2)

---

    From inequality(1)：
         X ≥ 261.620466
    From inequality(2)：
         X ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

---

    From inequalities (1) and (2)
         X ≥ 261.620466    (3)

---

    The final solution set is :
         X ≥ 261.620466
