Question 474016: what are the x,y,z coordinates of -7x-8y+2z=-6
-8x-2y-4z=-12
-3x-9y+5z=6
Answer by Edwin McCravy(20055) About Me  (Show Source):
You can put this solution on YOUR website!
(x,y,z) = (6,-6,-6)

If you want to know how to solve that system, post the system
again stating which of the many different ways to solve systems
of equations you are presently studying.
