how would you solve for 0<-6k-6<6? Is it an or, or an and problem?

Question

0<-6k-6<6

what is the first step, and how do i know where to begin?

Answer 1

 

 0<-6k-6<6

I think for this question, you would re-arrange so it is x < k < y, so x is by its self.

Without giving too much away, remember that if you are multiplying by a negative, the greater than signs flip to smaller than! 

 

SPOILER: if you want the answer to check it is right, it is below...
