Answer 3

It seems like you've provided a mathematical expression: (a-b-c)-(a-d)+d-(b-c). To simplify this expression, let's break it down step by step:

1. Start with (a-b-c). This means subtract b and c from a, which can be simplified to a - b - c.

2. Next is (a-d). This means subtract d from a, which gives you a - d.

3. Then we have d as a standalone term.

4. Lastly, (b-c) means subtract c from b, resulting in b - c.

Now let's put it all together:

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

Distribute the negative sign in front of the parentheses:

a - b - c - a + d + d - b + c

Combine like terms:

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

Simplifying further:

-2b + 2c + 2d

So, the simplified form of the expression (a-b-c)-(a-d)+d-(b-c) is -2b + 2c + 2d.
