D. 8 is attached to 3n by subtraction.

By subtracting 8 from both sides of the equation, Jonny is isolating the term 3n on one side of the equation. This step allows him to focus on solving for n without any constant terms attached to it.

The correct answer is D. 8 is attached to 3n by subtraction.

To solve the equation 8 + 3n = 20 for n, Jonny wants to isolate the variable n on one side of the equation. By subtracting 8 from both sides of the equation, he can remove the constant term (8) from the left side. This allows him to rewrite the equation as 3n = 20 - 8, which simplifies to 3n = 12.
