Answer 5

We are.

Answer 6

That means we want a to be by itself.

Answer 7

a+4<3

That means for this part we want to get rid of that 4 in the left hand side. How do we do that?

Answer 8

subtract it on both sides

Answer 9

Yes

a+4<3
a+4-4<3-4
a<3-4
a<-1

Answer 12

Yeah and do the same thing for the last part

Answer 13

a+1<8

subtract 1 from both sides

Answer 14

a+1<8
a+1-1<8-1
a<7

Answer 15

Now you have both parts. Look at the answer choice and see which one has both of the parts just like we solved them
