1. 9a+2b-8a-3b

 

To make things easier, put like terms together (so according to their unknown).

  9a+2b-8a-3b ≡ 9a-8a+2b-3b

 

Now you can easily see what to subtract, and what to add.

  9a-8a+2b-3b

eg: 9a-8a = 1a (or 'a')

      2b-3b = -1b (or '-b')

 

Which means the simplified format for 9a+2b-8a-3b is a-b.

 

 

2. 9a+5b+7a+8b

 

ans = 16a+13b
