Hey,

I have a question that I'm not sure how to approach at all. The question is:

Let

S={[[-1],[2],[1]] , [[3],[1],[2]] , [[1],[5],[4]] , [[-6],[5],[1]]}

and

v=[[-5],[3],[0]]

Is v in span(S)?

So i know that a set of vectors ie. v, spans a subspace, S, if every vector in S can be written as a linear combination of vectors in v.

Thanks in advance for any help you might be able to give!!
