See a solution process below:

First, evaluate the terms within the two sets of parenthesis:

#16 - 5 * (color(red)(4 - 1)) + 3 * (color(blue)(5 - 2)) =>#

#16 - 5 * 3 + 3 * 3#

Next, execute the two multiplication operations:

#16 - color(red)(5 * 3) + color(blue)(3 * 3) =>#

#16 - 15 + 9#

Now, execute the addition and subtraction operations from left to right:

#color(red)(16 - 15) + 9 =>#

#1 + 9 =>#

#10#
