Answer by richwmiller(17219) (Show Source): You can put this solution on YOUR website!
x=0,y=-2,z=3
add #2 and #3
subtract that result from #1
you should now have just y and z in that equation
multiply #2 by-2
add that to #3
you should have another with just y and z
now you should be able to solve those two for y and z
