What do you think is your first step?
OpenStudy (anonymous):
2(q -22) = 2q - 44?
OpenStudy (solomonzelman):
Focus on this part pf the equation for a second, can you factor it out.
2(q -22)
OpenStudy (anonymous):
2q - 44
OpenStudy (solomonzelman):
Yep! So what does your equation look like right now?

q + 12 - 2q - 44
OpenStudy (solomonzelman):
I don't get where do you get that from?
OpenStudy (solomonzelman):
Oh, and that is >0 see!
OpenStudy (anonymous):
-q + -32 > 0
OpenStudy (solomonzelman):

really?
OpenStudy (solomonzelman):
-q>32 or q<-32 which one?
OpenStudy (solomonzelman):
I multiplied by -1
OpenStudy (anonymous):
q>-32
OpenStudy (solomonzelman):
Close, but when you multiple an inequality times a negative number it flips over, becaomes the opposite, from more than to less than and vica versa.

Do you know why is this true?
OpenStudy (anonymous):
oh, ok and no
OpenStudy (solomonzelman):
Think logically, lets say you have 2>-3 right if you multiply by -1
would you be getting -2>3 or -2<3
OpenStudy (anonymous):
ok, i get it now, it makes since, that was one of those 'duh-huh' moments
OpenStudy (solomonzelman):
cool, more help?
