Test for consistency of the following system of linear equations and if possible solve: x + 2 y − z = 3, 3x − y + 2z = 1, x − 2 y + 3z = 3, x − y + z +1 = 0 . From the three examples above, we define the following terms. In mathematics, a system of linear equations (or linear system) is a collection of one or more linear equations involving the same set of variables. For example, + − = − + = − − + − = 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 are simultaneously satisfied.
