I HATED this as a boy. Alright, so I'm not going to give you all the answers, but i'd really like to help. Now, I assume you know how to solve equations algebraically, correct? well, inequalities are really similar, except instead of equals signs theres a < or an >, and theres more than one sometimes. for example, you should know that

6h=12

(6h)/6=(12)/6

h=2

its the same thing for inequalities!

6h<12

(6h)/6<(12)/6

h<2

if theres more than one symbol act like they're all equals signs (x=y=z)

8 < 2v-4 < 16

+4 +4 +4

12 < 2v < 20

/2 /2 /2

6< v < 10

and all that means is that V is between 6 and 10! so if you're graphing it on a number line, shade all the numbers between 6 and ten.

hope i helped!

omg sorry i learned this in 7th grade (last year) but now i forgot :(
