- 8 - 7 x > 6 Add 8 to both sides
- 8 - 7 x + 8 > 6 + 8
- 7 x > 14 Divide both sides by - 7

Remark:
When you multiply or divide inequality by a negative number you must change the direction of the inequality.
________________________________________
- 7 x / 7 < 14 / - 7
x < - 2
I did change the direction of the inequality.
I got the same answer you had as shown above, but the way the question is asked
when asking the value , I may be interperting the question wrong but if it is saying x<-2
wouldn't the answer be c= -3 since they are just asking for a value and not
the inequality answer.
CONFUsed about how it is written but knew how to do the actual work
Thanks
