no...but remember you can check for yourself, plug in those values

.... that was my line panlac lol

my bad... I can delete it

no need to delete :)

is this cramer rule? or row operations?

I think row of operations is the way to go.

yeah you have to divide the whole row by 5 then

hey cutie,have u been taught matrix inversion?which makes the solution much simpler.....

Well when we row reduce we want every number bellow that 1 to be a zero

Why would you multiply the first row by two?

Oh wait, nevermind! I gotcha now!

|dw:1344704116600:dw|

|dw:1344704166215:dw|

then divide the second row by 8.20 and then subtract the the first row by the second.

so the bottom row would be 0 1 -1 ?
And would that give you..
1 2/5 13/5 ?

so I then multiply the second row by\[\frac{3}{5}\]and then add it to the first row

|dw:1344704521394:dw|

|dw:1344704554208:dw|

|dw:1344704592083:dw|

multiply the second row by \[\frac{5}{3}\]now to get them back to 1

|dw:1344704647344:dw|

And I made a mistake I left out a negative sign here|dw:1344704797494:dw|

Oh, so when you multiply and add and what not, does it not apply to the first number in the row?

And when you add or subtract a zero from a number it stays the same.

Okay, I gotcha. Thanks for the explanation. :) It really helped!

No problem sorry for the messy work hope you could understand it .

I did :)
