See the entire solution process below

Explanation:

Step 1) Add color(red)(19) to each side of the equation to isolate the n term while keeping the equation balanced:

-12n - 19 + color(red)(19) = 77 + color(red)(19)

-12n - 0 = 96

-12n = 96

Step 2) Divide each side of the equation by color(red)(-12) to solve for n while keeping the equation balanced:

(-12n)/color(red)(-12) = 96/color(red)(-12)

(color(red)(cancel(color(black)(-12)))n)/cancel(color(red)(-12)) = -8

n = -8
