-2 ( s - 7)  >  4s + 8

 

-2s + 14  > 4s + 8

 

6 > 6s

 

1 > s

 

Or we can read this as

 

s < 1

 

(-inf, 1 )

Thanks, that actually makes sense I wasnt thinking about it the right way ūü§¶

But what I mean is find all the possible numbers that could equal s, rereading the question may help.

All the possible  numbers  are those from  - infinity  up to, bur not including 1

 

We obviously cannot list every value
