x = -3, x = 4.5
x = 3, x = 9
x = -3, x = 9
No solutions
OpenStudy (keyonsay):
x=9,-3
OpenStudy (anonymous):
can you explain it please?
OpenStudy (anonymous):
So the two lines are called absolute lines and they make every thing inside them positive
OpenStudy (anonymous):
So the news equation would be-2x+6=12

Do you understand how I got that?
OpenStudy (anonymous):
yes, please go on :)
OpenStudy (anonymous):
Okay now subtract 6 from both sides so it would be -2x=12
OpenStudy (anonymous):
Then divide -2 from bothes sides so now your left with x=-6!!!
OpenStudy (anonymous):
so its not what keyonsay said?

No

so its no solution?

Is it multiple choice or do you have to solve it (the question)
OpenStudy (anonymous):
x = -3, x = 4.5
x = 3, x = 9
x = -3, x = 9
No solutions
OpenStudy (anonymous):
multiple choice, those are the choices

Hmmm okay
OpenStudy (anonymous):
Oh oh ohhh i got it sorry you would plug in the numbers into the absolute value equation and see if it equaled to 12 not solve it
OpenStudy (anonymous):
so what is the correct answer?
OpenStudy (anonymous):
I'm working on it just a sec
OpenStudy (anonymous):
It would be the third one
