Question

anonymous · Answer

Have you figured out what A is in the example I've been begging you to solve?

anonymous · Answer

yeah i got it. thanks

anonymous · Answer

Ok, cool.  So let's solve it over here:   Let A = 5x+2

So.... if we have |A| = 13, what do we do to solve?

anonymous · Answer

-13=5x+2=13   solve for both sides to get both answers

anonymous · Answer

are you there hellowagner

anonymous · Answer

yeah, i just don't know the answer

anonymous · Answer

set 5x+2 equal to 13 and -13 and solve for both answers. tell me what you get

anonymous · Answer

@Hellowagner:  You told me that you solved my earlier example...  "yeah i got it. thanks"

I'm getting the impression you didn't. :/  If you don't understand how to solve something like |A| = 13, you won't be able to pass your exam.  Just tell me:  If you have |A| = 13, what two values can A equal?  I'll teach you more once you tell me the two answers.

anonymous · Answer

-13 and 13   ?

anonymous · Answer

That's right, hix, but we need hellowagner to figure that out. :(
I'm *trying* to teach it, but she's dodging the question for some reason.
