Answer 3

To solve the given expressions, I'll assume that the variables are real numbers. Let's proceed step-by-step:

1. c + (a + b)
2. c - (a - b)
3. (a - b) - (c - d)
4. (a - b) + (c - d)

Let's simplify each expression:

1. c + (a + b) = c + a + b

2. c - (a - b) = c - a + b

3. (a - b) - (c - d) = a - b - c + d

4. (a - b) + (c - d) = a - b + c - d

If you have specific values for the variables (a, b, c, and d), you can substitute them into the expressions to get the numerical results. Otherwise, these are the simplified forms of the given expressions.
