Questions:

Solving Linear Systems of Equations : Gaussian Elimination and Cramer's Rule

1. Solve the following linear system using Gaussian elimination.

Show work.

                              2y + z = 4
                              x+ y +z = 6
                              2x + y + z = 7

2. Solve the following linear system for x using Cramer's rule.

Show work.

                              4x - y + z = -5
