Respuesta :

For this case we have the following equation:
 5x / 6x + 3
 The denominator of the equation must be different from zero.
 Therefore, we have:
 6x + 3 = 0
 From here, we clear x:
 6x = -3
 x = -3/6
 x = -1/2
 Answer:
 
the nonpermissible replacement for the variable in this expression is:
 
B.-1/2
