Respuesta :
i put this into the app Photomath and got the answer of 9a+7 which might be right but so sure I’ve never done a problem like this before
5a-(-4a-7)
-(-4a-7) = 4a + 7
= 5a + 4a + 7
Then we will add the similar elements:
5a + 4a = 9a
Plus the seven we had:
Final answer: 9a + 7.
I hope I helped.
If you have any questions, please let me know! :)
