Answer 3

Let's simplify the given expressions step by step:

Expression 1: (a - b) - (c - d)

Distribute the negative sign in the second set of parentheses: = (a - b) - c + d

Combine like terms: = a - b - c + d

Expression 2: -(-a - d) + (-c - b)

Distribute the negative sign in the first set of parentheses: = a + d + (-c - b)

Combine like terms: = a + d - c - b

Both expressions are now simplified. However, they are not equal to each other: a - b - c + d ≠ a + d - c - b

Therefore, the two expressions you provided are not equal.
