-8x+(-10y)-7x-15y = -8x - 10y - 7x -15y
= -15x - 25y
= -5( 3x + 5y)

-8x - 10y - 7x - 15y
combine like terms
-15x -25y
take a -5 out
-5(3x + 5y)

-15x-25y.
You add like terms. -8x and -7x= -15x
-10y and -15y= -25y
And that's how you get -15x-25y.
You can't do anything else with it....

= - 8x - 7x - 10y - 15y
= - 15x - 25y
= (-5).(3x + 5y)

-8x+(-10y)-7x-15y
-8x - 10y -7x -15y (note that + of - is -)
= -15x - 25y
= - (15x + 25y)
= - 5(3x + 5y)
