The correct reason is:
He needs to subtract 8 from both sides of the equation in order to isolate the variable, n, and solve for its value. By subtracting 8 from both sides, he eliminates the term 8 on the left side of the equation, leaving only 3n. This allows him to continue solving for n by dividing both sides by 3.
jonny is solving this equation for n: 8 +3n= 20 his first step is to subtract 8 from sides of the equation. why
8 is the first term in the equation
he needs to reverse the order of operations
8 is attached to 3n by subtraction
he needs to follow the order of operations
