## Description
Escriba una función para resolver \ (Ax = b \) usando la eliminación de Gauss y luego la sustitución hacia atrás. \ (A \) siendo una matriz \ (n \ veces n \). Además, \ (x \) y \ (b \) son \ (n \) por 1 vectores. Para mejorar la precisión, use pivote parcial y escalado.
## Instructions
## Tests
