Sun 13 Nov, 2005 07:55 pm - 2x+3y+4z=2
5x-2y+3z=0
x-5y-2z=-2
the equations should be
[b]2x+3y+4z=2
5x-2y+3z=0
x-5y-2z=-4

[b]2x+3y+4z=2
5x-2y+3z=0
x-5y-2z=-2[/b]
i eliminated z first and i did it like this
2x+3y+4z=2
2x-10y-4z=-10
which equaled 4x-7y=-6
then i eliminated z from these... (view)

my answer 2x+2y=-4? (view)
