rearrange the given inequalities so as to get x on its own and the it will be easy to see
need more help?
OpenStudy (vianne):
Wait, I don't get it.. Can you give me an example on how to do that?
OpenStudy (cwrw238):
try no 1:-
-3x + 10 > 4
OpenStudy (cwrw238):
-3X + 10 -10 > 4 - 10
-3x > -6
OpenStudy (vianne):
That was a bit confusing...

divide both sides by -3
x < 2 (you flip the equality sign when dividing by a negative)
OpenStudy (cwrw238):
sorry i'm only sending small posts but I'm having problems
OpenStudy (vianne):
Okay. So -3 divided by 10 is -.3 and -3 divided by 4 is -.75
OpenStudy (vianne):
I have a feeling that I did this wrong.

Yes! I still don't get number 1! >.<
OpenStudy (dmndlife24):
Okay...for no. 1 we have -3x + 10 > 4
We need to get x by itself, right?
We do this by subtracting 10 from both sides like this...|dw:1423842117996:dw|
the 10s cancel on the left side
