[ 1/1Inequality]
    Assignment:Find the solution set of inequality (x+7)/(8-2x) >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         ( x + 7 ) / ( 8 - 2 * x ) >0         (1)
        From the definition field of divisor
         8 - 2 * x ≠ 0        (2 )

    From inequality(1):
         -7 < x < 4
    From inequality(2):
         x < 4 或  x > 4

    From inequalities (1) and (2)
         -7 < x < 4     (3)

    The final solution set is :

         -7 < x < 4
