Re: If x>5 and (4x+y)=8, which of the following must be true? [#permalink]

But y<-10 does contain all numbers in y<-12. y=-11<-10.

In contrast, y<-14 does not include all numbers in y<-12 (the inverse is true though). Y could be -13 for example.

I'm not sure whether the question is asking for a subset of y<-12 or if we need to find a set that includes y<-12


Thank you for pointing it out. I have updated my response and added an image also for better understanding of the solution.
