Quick Answer
Para resolver el sistema de ecuaciones, se utiliza el método de determinantes. Se formatean las ecuaciones en una matriz de coeficientes y una matriz de constantes. Luego, se calcula el determinante de la matriz de coeficientes y, si es distinto de cero, se obtiene la matriz inversa. Finalmente, se multiplica la matriz inversa por la matriz de constantes para obtener la solución del sistema.
