-8-7x>6

It is multiple choice

A=-1

b=-2

c=-3

d=2

I did this: -8-7x>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 + 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

**b6**, Friday, January 4, 2013 at 7:28amI 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
