is this correct @Mertsj @jim_thompson5910 ?

Answer 1

yes, but your job is to solve for \(y\) not \(-y\)

Answer 2

if \(-y>4\) then \(y<-4\)

Answer 3

ohhh, so switch it?

Answer 4

at this step
\[-7y>28\] you can divide by \(-7\) and change the sense of the inequality to get \(y<\frac{28}{-7}\iff y<-4\)

Answer 5

Ohhh, Okay. :) I understand now.

Answer 6

when you multiply / divide by a negative number, change the direction of the inequality
