Equation to Matrix

A system of linear equation is a collection of one or more linear equations involving the same set of variables. For example 3*x + 2*y - z = 1 2*x - 2*y + 4*z = -2 -x + 0.5*y - z = 0 is a system of three equation in three variable 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. A solution to the system
