The Geometry of Linear Equations
ocw.mit.eduThe fundamental problem of linear algebra is to solve n linear equations in n unknowns; for example: 2x − y = 0 −x + 2y = 3. In this first lecture on linear algebra we view this problem in three ways. The system above is two dimensional (n = 2). By adding a third variable z we could expand it to three dimensions.
