So you need to find three numbers divisible by 9 right? Explain the question a bit more. Like 3 sperate numbers that are divisible by 9 or 3 numbers that add up to a total that is divisible by 9?
Remember PEMDAS Do parentheses, results in 25. So whats left is 87-25*(-3)+9 Then you multiply -25 by -3, answer is 75. 87+75+9 Add all of them up. 171 The answer is 171!
