Hi I need help on solving a 3parameter simultaneous equation -2.006x-0.5y-0.7z=0 -0.5x-2.606y+1.1z=0 -0.7x+1.1y-0.906z=0 I need to solve for x, y and z. Can anybody explain how I would go about this? Thanks

Hi If the 3 equations are linearly independent (and it seems to be the case) then (x=0,y=0,z=0) is the only solution
I forgot to say that x, y and z cannot equal 0.

Ok so say I have a singular matrix and I want to solve for x, y and z. How would I do this?

Would yo do it by reducing the variables i.e. eqn1 -2eqn2 and reducing it to two variables?
