See a solution process below:

Using PEDMAS, first, execute the operation within the Parenthesis:

#(color(red)(8) - color(red)(10)) * 1.5 + (-5) =>#

#-2 * 1.5 + (-5)#

Next, execute the Multiplication:

#color(red)(-2) * color(red)(1.5) + (-5) =>#

#-3 + (-5)#

Remove the number from the parenthesis being sure to handle the sign correctly, then execute the Subtraction:

#-3 + (-5) =>#

#-3 - 5 =>#

#-8#
