See a solution process below:

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

$(8 - 10) \cdot 1.5 + (- 5) \Rightarrow$ $(color(red)(8) - color(red)(10)) * 1.5 + (-5) =>$

$- 2 \cdot 1.5 + (- 5)$ $-2 * 1.5 + (-5)$

Next, execute the Multiplication:

$- 2 \cdot 1.5 + (- 5) \Rightarrow$ $color(red)(-2) * color(red)(1.5) + (-5) =>$

$- 3 + (- 5)$ $-3 + (-5)$

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

$- 3 + (- 5) \Rightarrow$ $-3 + (-5) =>$

$- 3 - 5 \Rightarrow$ $-3 - 5 =>$

$- 8$ $-8$
