\[9<-x+3\] add \(x\) to both sides, get \(x+9<3\) then subtract \(9\) and finish with
\[x<-6\] graph that one
OpenStudy (lifeisadangerousgame):
Is that right?
OpenStudy (lifeisadangerousgame):
If it is, could you help me on two more? If not, could you tell me what I did wrong? (and then help me on two more? xD)
OpenStudy (anonymous):
yes, that is right, what you did

Awesome, thank you!
OpenStudy (lifeisadangerousgame):
I tried
4 < x + 7 < 8
-7 -7 -7
Am I going in the right direction?
OpenStudy (anonymous):
yes
OpenStudy (lifeisadangerousgame):

-3 < x < 1

yes

Whoop!:DD Last one :3
OpenStudy (anonymous):
this one is a trick
OpenStudy (anonymous):
if you subtract \(3\) you get \(|2x|<-7\) but this is impossible because the absolute value of anything is not negative
no solution for this one
OpenStudy (lifeisadangerousgame):
ooh, that's clever >.>
