The correct answer is: 8 is attached to 3n by subtraction.
By subtracting 8 from both sides of the equation, Jonny eliminates the constant term on the left side of the equation (8) and isolates the variable term (3n) on that side. This allows him to solve for n by performing the appropriate operations on the isolated term.
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.
