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

By subtracting 8 from both sides of the equation, Jonny eliminates the constant term on the left side of the equation (8) and isolates the variable term (3n) on that side. This allows him to solve for n by performing the appropriate operations on the isolated term.

The correct answer is:

8 is attached to 3n by subtraction.

When solving an equation, the objective is to isolate the variable on one side of the equation. In this case, Jonny wants to isolate the variable n. By subtracting 8 from both sides of the equation, he can remove the constant term on the left side and simplify the equation, which will help him solve for n.

The correct option is: He needs to reverse the order of operations.

To solve the equation 8 + 3n = 20, Jonny needs to isolate the variable n on one side of the equation. Currently, the equation has the term 8 added to the term 3n. In order to remove the 8 from the left side, Jonny needs to perform the inverse operation, which is subtraction.

By subtracting 8 from both sides of the equation, Jonny is essentially "undoing" the addition of 8 from the left side, which leads to the equation becoming 3n = 12.

This step is necessary to simplify the equation and bring it closer to the final solution.
