okay so for the first one it's 3b-16

but when you see b=8 you would rewrite it as 3×8- 16 and once you do that you should have the answers you do the same thing for the rest of them :)
All you do is replace the a’s and b’s in the expressions with the values they give you.

For example, for 3b - 16, you put 3(8) - 16 because they state that b = 8.

Message me if you need more help
