## Homework Statement

Suppose I have the augmented matrix

0 -1 0 | 0

0 -6 3 | 0

0 -1 0 | 0

## Homework Equations

which equates to -y = 0 and -6y + 3z = 0.

## The Attempt at a Solution

Would the solution be that x, y and z all equal 0?

Or do I need to let the missing variable, x = s and free variable z = t, so the solution is

1 0

s[ 0 ] + t [ 0.5 ]

0 1

(even though I know y = 0 and therefore the free variable must(?) be 0 ) ?

Thanks.
