Find the nonpermissible replacement for the variable in this expression.

5x/6x+3

A. - 2

B.-1/2

C. 0

D. 1/2

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
