See the entire solution process below

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#
