number of integral value of x that do not satisfy equation x-7/x-9>0

the given inequality is 
x-7x-9>0critical points are at x=7 and x=9from wavy curve method, we havex(-,7)(9,)at x =7 and x=9 in-equality does not hold.therefore7,8,9 are the integral values of x , that do not satisfy equation.the number of integral values , that do not satisfy the equation = 3

hope this helps you
