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

By subtracting 8 from both sides of the equation, Jonny can isolate the term with the variable, 3n, so that he can solve for n.

The correct answer is B. 8 is the first term in the equation.

When solving an equation, the goal is to isolate the variable, in this case, "n," on one side of the equation. By subtracting 8 from both sides of the equation, Jonny eliminates the constant term (8) from the left side, making it easier to isolate the variable.

Here's a breakdown of the steps Jonny is following:

1. The equation is 8 + 3n = 20.
2. Subtracting 8 from both sides of the equation:
(8 + 3n) - 8 = 20 - 8
Simplifying: 3n = 12

After completing this step, Jonny will likely continue solving for "n" by dividing both sides of the equation by 3, since 3n means "3 times n."

The correct answer is C. He needs to follow the order of operations.

When solving an equation, it is important to follow the order of operations (PEMDAS/BODMAS). In this case, subtracting 8 from both sides of the equation is the first step because it helps isolate the term with the variable, making it easier to solve for n.
