See a solution process below:

First, execute the operation within the parenthesis:

#1[8 - 4(color(red)(4) - color(red)(5))] => 1[8 - 4(-1)]#

Next, execute the Multiplication within the brackets:

#1[8 - color(red)(4)(color(red)(-1))] => 1[8 - (color(red)(-4))] => 1[8 + 4]#

Then, execute the Addition within the brackets:

#1[color(red)(8) + color(red)(4)] => 1[12]#

Now, execute the remaining Multiplication operation:

#1[12] => 12#
