Show that the vectors u [-1 1] v [2 1] w[3 3] are linearly dependent.

So, linearly dependent means that there is a solution for A,B,C that doesn't involve all zero's right?

So, -a + 2b + 3c = 0 and a + b + 3c = 0

I just solve these linear system of equations to show that the vectors are linearly dependent? Or am I completely wrong?

Thank you
