unless you actually ahve to go thru the process .. just input the options to determine the correct one

  • amistre64
and you seem to be missing a y part in the first one

do you have to run it by hand? or can you use a calculator like a ti83?

  • ExplainItLikeImFive
I can use a calculator.

I don't know how to use the Gauss-Jordan elimination method. Is there a different way of doing it?
amistre64
  • amistre64
what kind of calculator you got?
amistre64
  • amistre64
and yeah, there are other ways to approach it

go to your matrix functions and setup a 3x4 matrix to rref

2nd, math is the key presses for a ti83

If i did this right, I would choose D.

rref{{3,-7,-7,7},{6,4,-3,67},{-6,-3,1,-62}}

reworking......

  • ExplainItLikeImFive
Didn't even come close that time.
amistre64
  • amistre64
your setup and the options do not match
ExplainItLikeImFive
  • ExplainItLikeImFive
So none of the choices are correct?
amistre64
  • amistre64
nothing matches up ... so i do not see any correct solutions
amistre64
  • amistre64
i might have the first equation off tho, it that spose to be a -7 in there? or a -7y?
amistre64
  • amistre64
now its good http://www.wolframalpha.com/input/?i=rref%7B%7B3%2C0%2C-7%2C14%7D%2C%7B6%2C4%2C-3%2C67%7D%2C%7B-6%2C-3%2C1%2C-62%7D%7D
ExplainItLikeImFive
  • ExplainItLikeImFive
I think the first equation should be 3x - 7y - 7z = 7 not 3x - 7 - 7z = 7
ExplainItLikeImFive
  • ExplainItLikeImFive
Aha, so it would be D after all.
amistre64
  • amistre64
the first equation is good as is with the options available
