solve y = 12x + n for n need help please

For this, just subtract both sides by 12x and your answer will be [tex] y-12x=n [/tex]
y = 12x + n
You want to isolate the variable n on one side of the equation. In order to do this, you need to subtract 12x from both sides of the equation.
y - 12x = n
Rewrite this with n in the front.
