Answer 2

Sure, I can help you with that expression. It seems like you want to perform vector addition. To add the two vectors, you need to add their corresponding components. Here's how you can do it step-by-step:

First vector: -(6, 3a + 2b) Second vector: +(4, 7b - a)

To add the vectors, you add their respective components:

1. Add the x-components: -6 + 4 = -2

2. Add the y-components: (3a + 2b) + (7b - a) = 3a + 2b + 7b - a = 3a - a + 2b + 7b = 2a + 9b

Now, the result of the vector addition is:

Resultant vector: (-2, 2a + 9b)

So, the final expression after performing vector addition is: -(6, 3a + 2b) + (4, 7b - a) = (-2, 2a + 9b)
