The correct answer is A: he needs to follow the order of operation.
By subtracting 8 from both sides of the equation, he is using the inverse operation of addition to isolate the variable n. This is done in order to simplify the equation and solve for n.
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)
A:he needs to follow the order of operation
B:8 is the first term of equation
C:he needs to reserve the order of operation
D:8 is attached to 3n by subtraction
