-5<1-2k<3
subtract one
-6<-2k<2
divide by -2
3>k>-1
So your latter is correct, as I see it. And, your first is correct. Both are correct, both are identical
What's the solution for -5 < 1 - 2k < 3?
Is it 3 > k >-1 or is it -1 < k < 3?
I'm not sure if you have to switch the order of the numbers also when you're dividing it by a negative number..
