Answer 3

To simplify the expression (-a - b) - (c + d) - a + b, you can follow these steps:

1. Distribute the negative sign through the first set of parentheses: -a - b - (c + d) - a + b

2. Now, distribute the negative sign through the second set of parentheses: -a - b - c - d - a + b

3. Combine like terms. The -a and -a can be combined, and the -b and b can also be combined since they cancel each other out: (-a - a) + (-b + b) - c - d

4. Simplify further: -2a + 0 - c - d

5. Finally, simplify the expression further by combining like terms: -2a - c - d

So, the simplified expression is: -2a - c - d
