[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1+16*x/(x+2000)+0.8+4 >= (1+16*x/(x+2000)+0.15+4)*1.1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
        1 + 16 * x / ( x + 2000 ) + 0.8 + 4 >= ( 1 + 16 * x / ( x + 2000 ) + 0.15 + 4 ) * 1.1         (1)
        From the definition field of divisor
         x + 2000 ≠ 0        (2 )
        From the definition field of divisor
         x + 2000 ≠ 0        (3 )

    From inequality(1):
         x ≤ 184.300341
    From inequality(2):
         x < -2000 或  x > -2000
    From inequality(3):
         x < -2000 或  x > -2000

    From inequalities (1) and (2)
         x < -2000 或  -2000 < x ≤ 184.300341     (4)
    From inequalities (3) and (4)
         x < -2000 或  -2000 < x ≤ 184.300341     (5)

    The final solution set is :

         x < -2000 或  -2000 < x ≤ 184.300341
