[ 1/1Inequality]
    Assignment:Find the solution set of inequality (2x-0.9)(8x+46.02)/(5.4+x) >75.75 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         ( 2 * x - 0.9 ) * ( 8 * x + 46.02 ) / ( 5.4 + x ) >75.75         (1)
        From the definition field of divisor
         5.4 + x ≠ 0        (2 )

    From inequality(1):
         -5.597719 < x < -5.4 或  x > 5.029594
    From inequality(2):
         x < -27/5 或  x > -27/5

    From inequalities (1) and (2)
         -5.597719 < x < -5.4 或  x > 5.029594    (3)

    The final solution set is :

         -5.597719 < x < -5.4 或  x > 5.029594
