Answer 3

Let's simplify the expression step by step:

(a + b - c) - (a - b + c)

First, distribute the negative sign inside the parentheses:

a + b - c - a + b - c

Next, combine like terms:

(a - a) + (b + b) - (c + c)

The terms (a - a) and (c + c) cancel out because they are equal to zero:

0 + 2b - 0

Simplifying further:

2b

Therefore, the expression (a + b - c) - (a - b + c) simplifies to 2b.
