Answer 1

@blondey_315 is the top line the question and everything below it your work?

Answer 2

@GodGirl360 The top line iis the question and below are the answer choices

Answer 3

ok. Lets take this step by step. algebra is basically just a balance. If you add something to one side you have to add it to the other.

In x+8<3, you want to isolate the x. that means get rid of the 8, so you have to take the opposite of what it's doing(addition) and as i mentioned earlier you have to do it on the other side as well. So what's the answer to x+8<3?

Answer 4

@blondey_315

Answer 5

hm... you would have to take 8 from both sides correct?

Answer 6

yes @blondey_315

Answer 7

soo x<-5

Answer 8

Great! Now do the same thing with x+9>-4

Answer 9

x+9>-4
-9 -9
x>-13

Answer 10

Awesome! Do you have anything else you don't understand @blondey_315?

Answer 11

Thank you! and I do if you don't mind!

Answer 12

Ok, what is it?(thnks for the medal)

Answer 13

No problem! and here it is~
Solve 3n + 11 < 17 or -3n > 12. Which is the best description of the solution set?
n < 2 or n > -4
n < 2 or n < -4
n < 2
n < -4

Answer 14

For 3n+11<17, just do what you did in the last problem and subtract. Then you'll have 3n<6. 3n is using multiplication, so you need to use division.(and be sure to use it on both sides)

Answer 15

For -3n>12, just do division again and be sure to remember to mind the negative sign. (-+-= posistive, +++=Positive, -++= negative)

Answer 16

okie soo
3n<6
3/n 3/6
n < 2?

Answer 17

You got that right @blondey_315.

Answer 18

-3n>12
-3/n -3/n
-n > -4

Answer 19

Remember -+-=positive. So when you took -3n/-3, you should get...

Answer 20

n?

Answer 21

yep, anything else you need?
