Ответ:2в

Answer 2

It seems like you've provided an algebraic expression. Let's simplify it step by step:

Given expression: -(а-в-7,4) + (-7,4+в+а)

Step 1: Distribute the negative sign to the first term within the parentheses: -а + в + 7.4 + (-7.4 + в + а)

Step 2: Group like terms: (-а + а) + (в + в) + (7.4 - 7.4)

The terms with variables that are being added to their negatives will cancel out, and the constant terms will also cancel out.

Step 3: Simplify: 0 + 2в + 0

Result: 2в

So, the simplified form of the given expression is 2в.
