(adsbygoogle = window.adsbygoogle || []).push({}); 3x1 + x2 + x3 = 0

6x1 + 2x2 + 2x3 = 0

-9x1 - 3x2 - 3x3 = 0

I'm not sure how to approach this problem. I've rewritten these equations as a matrix

[3 1 1]

[6 2 2]

[-9 -3 -3]

Reduced Echelon from gave me this

[3 1 1]

[0 0 0]

[0 0 0]

Am I approaching this the wrong way?

What should I do next? Please help.

Thank You.
