Explanation: PEMDAS
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
-3(4-9) + 6 -2(-8+5)
= -3(-5) + 6 -2(-3) p for parentheses first
= (15) + 6 (6) since we don't have exponents, we go to multiplication next
= 15 + 12 we do multiplication before addition, so we multiply first again
= 27 now we've added and simplified to an answer
The answer is 27.
