Solving Systems of Equations
(Angelo State University)
Solve the linear system of equations below using the elimination-substitution procedure. (Note: The student also needs to know how to apply matrix techniques using the augmented matrix in solving this and other similar linear systems of equations.)

The problem is complicated by the fact that there are infinitely many solutions. In fact, any point of the form (x, y, z) = (2z, 4z – 1, z), where z is a real number, is a solution.
