[ 1/1Inequality]
    Assignment:Find the solution set of inequality 250-[10000/x+20000/(x+60)] ≥17500/x+10000/(x+60) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
        250 - ( 10000 / x + 20000 / ( x + 60 ) ) ≥17500 / x + 10000 / ( x + 60 )         (1)
        From the definition field of divisor
        x ≠ 0        (2 )
        From the definition field of divisor
         x + 60 ≠ 0        (3 )
        From the definition field of divisor
        x ≠ 0        (4 )
        From the definition field of divisor
         x + 60 ≠ 0        (5 )

    From inequality(1):
         x ≤ -60 或  -32.57976 ≤ x ≤ 0
    From inequality(2):
         x < 0 或  x > 0
    From inequality(3):
         x < -60 或  x > -60
    From inequality(4):
         x < 0 或  x > 0
    From inequality(5):
         x < -60 或  x > -60

    From inequalities (1) and (2)
         x ≤ -60 或  -32.57976 ≤ x < 0    (6)
    From inequalities (3) and (6)
         x < -60 或  -32.57976 ≤ x < 0    (7)
    From inequalities (4) and (7)
         x < -60 或  -32.57976 ≤ x < 0    (8)
    From inequalities (5) and (8)
         x < -60 或  -32.57976 ≤ x < 0    (9)

    The final solution set is :

         x < -60 或  -32.57976 ≤ x < 0
