Hello everyone i'm confused if i'm setting these equations up right:(adsbygoogle = window.adsbygoogle || []).push({});

i have:

1 0 1

0 1 -2

0 0 0

so i said:

x + z = 0;

y - 2z = 0;

z = ? because its a whole row of 0's, so u have no info about what z could be

so i said let z = a;

x + a = 0;

y -2a = 0;

z = a;

x = a;

y = 2a;

z = a;

so let a = 1;

my nullspace is:

1

2

1

am i doing that right?
