color(purple)"n = - 3"n = - 3

Explanation:

color(magenta)("Subtract 12 on both sides:")Subtract 12 on both sides:

cancel12-12n= 48
cancel-12 color(white)(aaaa) -12

12 cancels out on the left side, and when you subtract 12 from 48 on the right you get 36:

-12n = 36

color(greeb)("Divide both sides by -12 to get n by itself.")

(cancel"-12"n)/cancel"-12"=(36)/-12

Now you are just left with n on the left side and -3 on the right side.

Therefore,
color(purple)"n = -3"
