A collection of linear equations is called a system of linear equations. Chapter 2 Linear Equations One of the problems encountered most frequently in scientic computation is the solution of systems of simultaneous linear equations. These are lecture notes for our 2-credit introductory linear algebra course. This formula works because if we multiply the two matrices on the left, we get the 2 1.
