## Algebra and Trigonometry 10th Edition

Gaussian Elimination: $\begin{bmatrix} 1 & 2 & |0\\ 1 & 1 & |6\\ 3 & -2 & |8\\ \end{bmatrix}$ ~ $\begin{bmatrix} 1 & 2 & |0\\ 0 & 1 & |-6\\ 0 & -8 & |8\\ \end{bmatrix}$ Back-Substitution: y = -6 -8y = 8 y = -1 Since y has two different solutions, there is no solution to the system. The system is inconsistent.
