None of the given responses provide the correct explanation.
The correct reason why Jonny subtracts 8 from both sides of the equation is to isolate the variable "n" on one side of the equation. By subtracting 8 from both sides, the equation becomes:
8 + 3n - 8 = 20 - 8
which simplifies to:
3n = 12
Jonny is solving this equation for n : 8 + 3n = 20 . His first step is to subtract 8 from both sides of the equation. Why?(1 point)

The correct response is:
He needs to isolate the variable "n" on one side of the equation in order to solve for it. By subtracting 8 from both sides of the equation, Jonny is able to eliminate the constant term on the left side and simplify the equation to 3n = 12.
