Answer:
The answer would be 26
Step-by-step explanation: (Broken down into 2 parts) 
-PART ONE- solving (12-7) x (8-5) -7 
(12-7) x (8-5) -7 (do whats in parentheses first) 
(5)x (3) -7 (multiply 5x3)
15-7 (subtract) 
ANSWER- 8
-PART TWO- solving (16-4) + (10 - 12 divided by 3)
(16-4) + (10 - 12 divided by 3) (do what is in parentheses) 
12 + 10-4 (add) 
22-4 (subtract)
ANSWER- 18
Now combine the two answers 18+8 and you get 26
Therefore, 26 is the final answer. 
Hope this helps!!
