Jonny is subtracting 8 from both sides of the equation because 8 is the first term in the equation and he needs to follow the order of operations.
The correct response is "8 is the first term in the equation."
When solving an equation, it is important to isolate the variable by performing inverse operations. In this case, Jonny wants to isolate the term with the variable (3n), so he needs to eliminate the other terms on that side of the equation. By subtracting 8 from both sides of the equation, with the goal of getting rid of the 8 term on the left side, he can isolate the term with the variable and continue solving for n.
