Which of the values is in the solution set for the inequality
-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

  • math - ,

    - 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

  • math - ,

    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
