See a solution process below:

First, evaluate the expression within the left absolute value function. Remember: minus a minus is a plus

#abs(color(red)(1) - color(red)(-3)) + abs(5) =>#

#abs(color(red)(1) + color(red)(3)) + abs(5) =>#

#abs(4) + abs(5)#

Next, execute both the absolute value functions. The absolute value function takes any term and transforms it to its non-negative form.

#abs(4) + abs(5) =>#

#4 + 5 => 9#
