Answer 3

Simplifying the Expression

To simplify the given expression A-(b-c+d)-c+(d+b-a), we can follow the order of operations (PEMDAS/BODMAS) and combine like terms. Let's break down the expression step by step:

1. A-(b-c+d)-c+(d+b-a)

2. A-b+c-d-c+d+b-a

3. A-b+b+c-c+d-d-a

4. A-a

5. A-a = 0

Therefore, the simplified expression is 0.

Simplifying the Second Expression

To simplify the second expression (a-b-c)-(a-d)+d-(b-c), we can follow the order of operations (PEMDAS/BODMAS) and combine like terms. Let's break down the expression step by step:

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

2. a-b-c-a+d+d-b+c

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

4. 0+0+0+2d

5. 2d

Therefore, the simplified expression is 2d.

Summary

The simplified expressions are: 1. A-(b-c+d)-c+(d+b-a) = 0 2. (a-b-c)-(a-d)+d-(b-c) = 2d
