If you do 12-3 divided by 3-6 it equal 5 so 5 would be the awnser

Answer:

The rational expression is equivalent to -3 when x is equal to 3.

Step-by-step explanation:

The rational expression is

[tex]\frac{12-x}{x-6}[/tex]

For [tex]x=3[/tex], we have

[tex]\frac{12-3}{3-6}=\frac{9}{-3}=-3[/tex]

Therefore, the rational expression is equivalent to -3 when x is equal to 3.
