Homework Statement


Find a basis for the subspace of R3 spanned by S={(42,54,72),(14,18,24),(7,9,8)}.

I am not sure what steps to take to solve this.

Any help would be great.

Do you know how to find a basis for a subspace in general?
 
I'm sorry. I figured it out. It was staring me right in the face and I was just to brain dead to get it. haha sorry.
