Answer 1

Ответ:

-2a-2b+3

Пошаговое объяснение:

3a+b-(8a-5b)+3a-b-7b+3

3a-8a-5b+3a-7b+3

Answer 2

Let's simplify the given expression step by step:

(3a + b) - (8a - 5b) + (3a - b) - (7b - 3)

First, distribute the negative sign inside each set of parentheses:

3a + b - 8a + 5b + 3a - b - 7b + 3

Now, combine like terms:

(3a - 8a + 3a) + (b + 5b - b - 7b) + (3)

-2a - 2b + 3

So, the simplified expression is: -2a - 2b + 3

This means that the original expression (3a + b) - (8a - 5b) + (3a - b) - (7b - 3) is equivalent to -2a - 2b + 3.
