Query: Linear Algebra for Dummies

It's too late for me, kids. I failed Linear Algebra, thanks in no small part to Professor Lawson's brilliantly absent-minded adventure to the depths of a kingdom of linear algebra. I bought the book as a requirement for the class. Now I will admit that Prof. Lawson kept it real with the phat 3D triangle art, but that's the only part of the book I understood. On page 35 there is this wicked diagram of some intersecting hyper-planes, but little did I know that the diagram was mislabelled because as we all come to know in linear algebra, when the number of linear equations is equal to the numberof unknowns in those equations, and if the rank of A equals the number of equations, then the system has infinite solutions, not a single one as indicated by the intersecting planes. Poor bastards.
