Answer 1

Ответ:

-(х+4)+(у-2)-(z-x)= -х-4+y-2-z+x= y-z-6

Answer 2

To simplify the expression -(х+4)+(у-2)-(z-x), we can follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction). Let's break down the steps:

1. Simplify the expression inside the parentheses: -(х+4) = -х - 4 (у-2) = у - 2 (z-x) = z - x

2. Substitute the simplified expressions back into the original expression: -х - 4 + у - 2 - (z - x)

3. Combine like terms: -х + у - z - 6 + x

4. Rearrange the terms: -х + x + у - z - 6

5. Combine like terms: (x - х) + у - z - 6

6. Simplify further: 0 + у - z - 6

Therefore, the simplified expression -(х+4)+(у-2)-(z-x) is у - z - 6.
