Answer 1

1)c - a - b я не знаю чи точно я в вчительки спиталась

Answer 2

C-a-bc
-c+a-bc
x-a+xb+c-d
10-a+b-c-d

Answer 3

Let's simplify each expression step by step:

1. Simplify the expression: C - (a + b) - c - (-a + b) We'll first remove the parentheses: C - a - b - c + a - b Now, group like terms: (C - c) + (-a + a) + (-b - b) Simplify: C - c + 0 - 2b Finally, we get: C - c - 2b

2. Simplify the expression: x - (a - b) + (c - d) Again, remove the parentheses: x - a + b + c - d Group like terms: (x - a) + (b + c) - d Finally, we get: x - a + b + c - d

3. Simplify the expression: 10 - (a - b) - (c + d) Remove the parentheses: 10 - a + b - c - d There are no like terms to combine, so the simplified form is: 10 - a + b - c - d

The simplified expressions are as follows:

1. C - c - 2b
2. x - a + b + c - d
3. 10 - a + b - c - d
