Jonny is subtracting 8 from both sides of the equation to isolate the variable term, 3n, on one side. This is done to solve for n.
which one
The correct answer is:
8 is the first term in the equation.
When solving an equation, it is often helpful to isolate the variable on one side of the equation. In this case, since 8 is the first term in the equation, subtracting 8 from both sides will help Jonny isolate the variable (n) on one side of the equation.
