Homework Help: Finding the basis for a subspace

  1. Nov 29, 2008 #1
    1. The problem statement, all variables and given/known data
    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?
