umm, what are the equations?
hi,
im trying to solve a set of equations by guassian elimination,
i got it this far
1 0 -1 2 0
0 1 2 3 0
0 0 0 0 1
sorry havent figured out how to use the maths tags yet.
should i have
X1 -X3 +2X4 = 0
X2 + 2X3 + 3X4 = 0
what about the last row?
hmm, this is looking a bit peculiar. I did a little something that went like this:
The equations we have are:
------>equation 1)
----->equation 2)
----->equation 3)
2)-3)=
but 10 is .
This implies that
As a result, the equations now become:
or
However, the values of and now conflict with equation two.
I don't think these equations have solutions....
