Answer 3

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's solve the expression step-by-step:

1. 27 ÷ 9 = 3
2. 3 × 3 = 9
3. (27 ÷ 9) × 7 = 3 × 7 = 21
4. 47 + 5 = 52
5. 52 - 9 = 43
6. 43 + 21 = 64
7. 64 - 14 = 50

So, the final result is 50.
