Answer 2

8<2b or 2b+15<5

Lets start with 8<2b

Start with switching the sides like this
2b>8 (you also flip the symbol)
Now divide both by 2
2b/2>8/2= (2b/2 will get crossed out and 8/2 is 4)
b>4

Now this one: 2b+15<5
Subtract 15 from both sides Since the opposite of addition is subtraction.
2b+15-15<5-15
Now solve:
2b<-10
now divide both sides by 2
2b/2<-10/2
=b<-5

Answer: b>4 or b<-5 A.
