... suppose Ax1 = Ax2 = b and x1! x2 then A(x1- x2) = Ax1 - Ax2 = b - b = 0 and for any scalar k we have A[x1- k(x1-x2)] = Ax1- k A(x1-x2) = b - k 0 = b so x1- k(x1-x2) is a solution of Ax = b for any scalar k as long as there are an infinite number of scalars [e.g. for a real vector space] there will b ...
