For this case we have the following expression:
 ((x-4) / (6)) / ((x + 1) / (7))
 Rewriting we have:
 7 (x-4) / 6 (x + 1)
 We observe that the expression is not defined for the values where the denominator is equal to zero.
 We have then:
 x + 1 = 0
 x = -1
 Answer:
 
The excluded value of the rational expression is:
 
A. -1
