[ 1/1Inequality]
    Assignment:Find the solution set of inequality 3.96/2y+3.96/(y+0.5)+2.5/y+3.5/y+3.5/(y+0.05) <100 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
        3.96 / 2 * y + 3.96 / ( y + 0.5 ) + 2.5 / y + 3.5 / y + 3.5 / ( y + 0.05 ) <100         (1)
        From the definition field of divisor
         x + 0.5 ≠ 0        (2 )
        From the definition field of divisor
        x ≠ 0        (3 )
        From the definition field of divisor
        x ≠ 0        (4 )
        From the definition field of divisor
         x + 0.05 ≠ 0        (5 )

    From inequality(1):
         y < -0.5 或  -0.467578 < y < 0 或  0.08847 < y < 50.370516
    From inequality(2):
         y < -1/2 或  y > -1/2
    From inequality(3):
         y < 0 或  y > 0
    From inequality(4):
         y < 0 或  y > 0
    From inequality(5):
         y < -1/20 或  y > -1/20

    From inequalities (1) and (2)
         y < -0.5 或  -0.467578 < y < 0 或  0.08847 < y < 50.370516     (6)
    From inequalities (3) and (6)
         y < -0.5 或  -0.467578 < y < 0 或  0.08847 < y < 50.370516     (7)
    From inequalities (4) and (7)
         y < -0.5 或  -0.467578 < y < 0 或  0.08847 < y < 50.370516     (8)
    From inequalities (5) and (8)
         y < -0.5 或  -0.467578 < y < -1/20 或  -1/20 < y < 0 或  0.08847 < y < 50.370516     (9)

    The final solution set is :

         y < -0.5 或  -0.467578 < y < -1/20 或  -1/20 < y < 0 或  0.08847 < y < 50.370516
