SISTEMA DE ECUACIONES
LINEALES DE 2X2
Un sistema de ecuaciones lineales de 2x2 es aquel sistema que consta de 2 ecuaciones con 2 incógnitas cada una a las que hay que hallarles su valor numérico. Los sistemas de ecuaciones lineales de 2x2 se pueden resolver de las siguientes formas o métodos:
1.) Método de reducción.
2.) Método de igualación.
3.) Método de sustitución.
4.) Método por determinantes.
Es un ejemplo de sistema de ecuación lineal de 2x2 la siguiente expresión:
ax+by=c (1)
mx+ny=p (2)
9x+7y=23
8x-5y=-2
Sol: (1, -2)
2x-5y=-11
7x+8y=38
Sol: (2, 3)
10x+9y=85
8x+7y=67
Sol: (4, 5)
9x-6y=-114
3x-2y=-38
Sol: (-8, 7)
