Question: 3x + 16y - 39z = -9 -8x - 17y + 27z = 24 -2x - 4y + 6z = 6 I have a question

3x + 16y - 39z = -9

-8x - 17y + 27z = 24

-2x - 4y + 6z = 6

I have a question on this Matrix. I solve this to be:

1, 0, 3 | -3

0, 1, -3 | 0

0, 0, 0 | 0

How do I write the answer in terms of 'z'?

x = -3z -3

y = 3z

Z = ???? ( I believe this to be zero? But, I got this answer wrong??)

Please help me write the solution for z

Thank you!
