hartnn · Answer

yes, you do.
and while doing that, don't forget to flip the sign (whenever you multiply or divide by the negative number)

hartnn · Answer

for example -2x < 5 gives 
x> -5/2

oh i thought you only did that when you divid by 2 negaives thank you!(:

hartnn · Answer

just to make sure u get this one correct, here it'll be x<-3

anonymous · Answer

@hartnn 
so that would be a closed circle and shaded to the left?

hartnn · Answer

if x could take that value, then there will be closed circle.
here x < -3, so x cannot take the value of -3 , it has to be less, so it'll be open circle.
left shading is correct :)
