[ 1/1Inequality]
    Assignment:Find the solution set of inequality x+【0.2*(x-0.3)】/(x-0.4)-0.3 >0.6 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         x + ( 0.2 * ( x - 0.3 ) ) / ( x - 0.4 ) - 0.3 >0.6         (1)
        From the definition field of divisor
         x - 0.4 ≠ 0        (2 )

    From inequality(1):
         0.4 < x < 1/2 或  x > 3/5
    From inequality(2):
         x < 2/5 或  x > 2/5

    From inequalities (1) and (2)
         0.4 < x < 1/2 或  x > 3/5    (3)

    The final solution set is :

         0.4 < x < 1/2 或  x > 3/5
