Hoot! You just asked your first question! Hang tight while I find people to answer it for you. You can thank people who give you good answers by clicking the 'Good Answer' button on the right!
the absolute value of x is 6. so x could be either 6 or -6
\[|x-3|=5\] \[x-3=5\] \[x-3=-5\] \[x-3=5 , x=8\] \[x-3=-5, x=-2\]
there are two. do you have one you would like to do?
yeah, the |x-3| = 5 one.
the problem is, I don't quite remember how to do the process. Could one help.
just remember when you remove the absolute value signs you have to write two separate equations
this is clear yes? because if i know \[|x|=78\] then x could be 78 but it could also be -78
yeah, I just looked that up, and it made sense. Now what if there's two variables, like |x-3| = 5, would the answer be, "2 or -2" ?
because if i know |x-3|=5 then what i know is that either x-3=5 or x-3=-5
the solution to the first one is x = 8, not x = 2. the solution to the second one IS x=-2
Ok. I kind of see what you did... Could you give me another one amongst those lines, so I can try it?
sure try |x+3|=7
The answer to the first one should be 4, and the second one, being (|x+3| = -7) would be -10?
yes . got it. write to equations, solve each individually
i meant write TWO equations
Yeah, for sure! (: It's just I'm a bit slow at first, but once I get it, I beast through all of them, lol. Btw, are there any equations like that, with THREE variables?
not usually. do you have one?
No, I just wanted to know so I could be prepared in case I get one of those.
you could have something like this: |x+2|=2x-5
and how would you solve that?
in which case you still have to write two equations but you have to be very very careful
you would write two equations. one would be: x+2=2x-5
the other would be: x+2=-(2x-5)
which of course means x+2=-2x+5
be careful when you take the negative to remember to put it in parentheses
alright, and so from there, what step is next?
just solve like any linear equation. \[x+2=2x-5\] \[2+5=2x-x\] \[7=x\]
or \[x+2=-(2x-5)\] \[x+2=-2x+5\] \[x+2x=5-2\] \[3x=3\] \[x=1\]
hey do you have time, ? because i have another question...
and btw, thanks a lot.
AWH, no satellite, dont forsake me right now! I got aaaaaa big TEST tomorrow!
one more and then i turn into a pumpkin
what's that mean?
go ahead and ask
never saw or read cinderella?
oh, yeah, aha.... but its only 10:44, doesn't that happen at 12?
eastern standard time
Interesting. Ok, anyways, sorry for delaying your transformation, but could you give me some heads up on solving prequalities?
even spell check doesn't like that
I don't know, the weird lady put one of the subjects we need to study, under "Solving prequaltities and graphing solution." Any ideas?
sorry never heard of them.
google hasn't either so i don't feel bad
Yeah, it doesn't even show up on google. !
Alright, well, you've been of great help! And I appreciate it. Thank you, who ever you are, and have a good one!
