Which of the values is in the solution set for the inequality
It is multiple choice
I did this: -8-7x>6
add 8 to each side
since it is less then -2 should the answer be c=-3
The way they ask the question I am not sure if the answer is b or c

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