Answer 3

Let's solve the expression step by step:

1. First, simplify the expressions within parentheses: 17 - 14 = 3 20 - 7 = 13

2. Now, substitute the simplified values back into the original expression: 20 - (17 - 14) - (20 - 7) = 20 - 3 - 13

3. Perform the remaining operations from left to right: 20 - 3 = 17 17 - 13 = 4

So, the final answer is 4.
