Question

(a-b-((-a+b)-(a-b)))=

Answer 1

Ответ:

=a-b-(-a+b-a+b)=a-b-(-2a+2b)=a-b+2a-2b=3a-3b.

Answer 2

Let's simplify the expression step by step:

a - b - ((-a + b) - (a - b))

First, simplify the innermost parentheses:

a - b - (-a + b - a + b)

Now, combine like terms:

a - b - (-a - a + b + b)

Simplify further:

a - b - (-2a + 2b)

Now, distribute the negative sign inside the parentheses:

a - b + 2a - 2b

Combine like terms again:

(a + 2a) + (-b - 2b)

3a - 3b

So, the simplified expression is:

3a - 3b
