Which of the values is in the solution set for the inequality
87x>6
It is multiple choice
A=1
b=2
c=3
d=2
I did this: 87x>6
add 8 to each side
7x>14
7/7>14/7
x<2
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
Thanks

 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
