Jonny subtracts 8 from both sides of the equation in order to isolate the term with \( n \). This is done to simplify the equation and solve for \( n \). The correct response would be:

8 is attached to 3n by addition.

This statement implies that in the equation \( 8 + 3n = 20 \), the 8 is added to \( 3n \), and by subtracting 8 from both sides, he can effectively isolate \( 3n \).
