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:

$-3 + (-5) =>$

$-3 - 5 =>$

$-8$
