Answer 2

Let's simplify each expression step by step:

1. 2(x+4) - 5 = 2x + 24 - 5 = 2x + 8 - 5 = 2x + 3

   3(y-1) - 8 = 3y - 31 - 8 = 3y - 3 - 8 = 3y - 11

2. 15 + (a + b) = 15 + a + b

   6 - (c - b) = 6 - c + b

3. (20 + x) + 10 = 20 + x + 10 = 30 + x

   30 - (x + 3) = 30 - x - 3 = 27 - x

Please note that the third expression you provided is incomplete. If you could provide the complete expression, I'd be happy to help you simplify it as well.
