Answer 2

Ответ:

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

Answer 3

To simplify the expression (a - b - c) - (a - d) + d - (b - c), you can start by distributing the negative sign inside each set of parentheses:

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

Now, you can combine like terms:

(a - a) + (d + d) + (-b - b) + (-c + c) = 0 + 2d - 2b + 0

Simplifying further:

2d - 2b

So, the simplified expression is 2d - 2b.
