HELLO !
Okay so what you do is eliminate the parenthesis in the equation because it really helps
So you would multiply 8 and b
Also multiple 8 and a
You would get 8b and 8a
Your equation would look like ...
2a + 8b + 8a = ...
Now you add the alike things in the equation
8a and 2a are the alike things.
Now you would have ...
10a + 8b = ?
