The Answer would be 2.8 because when you subtract -16 - 8 you get -24... then you divide that by 2 and you should have -12 + 25 / 5 + 1.... from there you can move the one from the end and add it to 25 and you get -12 + 26 / 5.... and all you have to do is simple math there... -12 + 26 = 14... and 14 / 5 == 2.8
ANSWER == 2.8
Hope that Helped
