Answer 3

To simplify the expression (2a + b) + (2a - b), you can use the distributive property to add like terms:

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

First, you can simplify the expression inside each set of parentheses:

1. (2a + 2a) = 4a
2. (b - b) = 0

Now, you can combine the simplified expressions:

4a + 0

Since adding 0 to any number doesn't change the number, the final simplified expression is:

4a
