[ 1/1Inequality]
    Assignment:Find the solution set of inequality [2.6/(1+x)*3]+[1.5/(1+x)] >8 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         ( 2.6 / ( 1 + x ) * 3 ) + ( 1.5 / ( 1 + x ) ) >8         (1)
        From the definition field of divisor
         1 + x ≠ 0        (2 )
        From the definition field of divisor
         1 + x ≠ 0        (3 )

    From inequality(1):
         -1 < x < 13/80
    From inequality(2):
         x < -1 或  x > -1
    From inequality(3):
         x < -1 或  x > -1

    From inequalities (1) and (2)
         -1 < x < 13/80     (4)
    From inequalities (3) and (4)
         -1 < x < 13/80     (5)

    The final solution set is :

         -1 < x < 13/80
