Elimination with Matrices - MIT OpenCourseWare
Elimination with matrices Method of Elimination Elimination is the technique most commonly used by computer software to solve systems of linear equations. It finds a solution x to Ax = b whenever the matrix A is invertible. In the example used in class, ⎡ ⎤ ⎡ ⎤ 1 2 1 2 A = ⎣ 3 8 1 ⎦ and b = ⎣ 12 ⎦ . 0 4 1 2

But for small matrices, it can be very worthwhile to know the inverse. We add three observations about this particular K 1 because it is an important example.
