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
2x + 2y + 3z = 10
5x - 2y + 6z = 1
