Let b be the vector such that B = [A b] , and let a1, a2, a3 and a4 be the columns of A.(adsbygoogle = window.adsbygoogle || []).push({});

Let m be the number of linearly independent columns of A, let k be the number of parameters (free variables), and let n be the total number of columns in A. In our example above, n = 4.

Do you suppose that this relationship m + k = n will be true for all systems of linear equations?
