Answer:

Diego's answer 4b+9b is correct:)

Step-by-step explanation:

Our first step is to combine like terms.

Causing you to combine 7a and -3a which gives you 4a because 7-3=4

Next, you would combine 5b and 4b which gives you 9b because 5+4=9

After you have combined like terms you would have your simplified equation 4b+9b causing Diego's answer to be correct!

Hope this helps!
