From the RREF it is clear to me that (2, 3, 0) are valid scalars for a linear combination and there are infinitely many such solutions. However, the answer in the back of the book suggests otherwise.
More than anything, I am asking for confirmation that my understanding is correct and that the provided answer is wrong.
