Homework Help: math

Posted by Es on Friday, December 28, 2012 at 8:57am.

I asked sue a question yesterday and don't understand the answer can you explain?
Here what it was
I think this question has a typo because none of the multiple choice answers fit.

The question is which of the following values is in the solution set of inequality 8-7x<-6?
A) -3 B)-2 C)2 D)-6

A if you plug in -3 you get
29<-6 no
B) 8+14<-6 no
c) 8-14<-6 so -6<-6 no
D) 8+42<-6 no
Did I do something wrong or are there no correct answers?
Thank you

8-7x<-6

-7x < -6 -8

-7x < -14

x = 2

SO WHEN SUE WROTE X=2 shouldn't it be
WHEN YOU SOLVE IT IS X<2
Then when you check it
8-7x<-6
8-7(2)
8-14<-6
-6<-6 IT DOESN'T WORK, PLEASE HELP ME UNDERSTAND HOW X=2 LIKE SUE SAID
THANKS
