Answer 3

Let's simplify the expression step by step:

(7a - b) - (3a - 2b) + 2(b - 4a)

First, let's distribute the negative sign (-) inside the parentheses:

7a - b - 3a + 2b + 2(b - 4a)

Next, let's simplify the expression inside the parentheses:

7a - b - 3a + 2b + 2b - 8a

Now, let's combine like terms:

(7a - 3a - 8a) + (-b + 2b + 2b)

Combining the "a" terms:

6a - 8a

-2a

Combining the "b" terms:

-b + 2b + 2b

5b

Putting it all together:

-2a + 5b

So, the simplified expression is -2a + 5b.
