Created page with "== Introduction == A system of linear equations (also known as linear system) is a collection of one or more linear equations involving the same variables. For example, \[ \begin{align*} 3x + 2y - z & = 1 \\ 2x - 2y + 4z & = -2 \\ - x + \frac{1}{2}y - z & = 0 \end{align*} \] is a system of three equations in the three variables x, y, z. A solution to a linear system is an assignment of values to the variables such that all the equations..."
