The correct answer is: 8 is attached to 3n by subtraction.
When solving an equation, the goal is to isolate the variable on one side of the equation. By subtracting 8 from both sides of the equation, Jonny is removing the constant term (8) from the left side so that only the variable term (3n) remains. This step allows him to more easily solve for n in the next steps.
Jonny is solving this equation for n : 8 + 3n = 20 . His first step is to subtract 8 from both sides of the equation. Why?
options:
8 is the first term in the equation.
He needs to reverse the order of operations.
He needs to follow the order of operations.
