1) 2x + 3y = 3 (6)
2) 5x - 6y = 3 (3)
Multiplico las ecuaciones por los números indicados.
12x + 18y = 18
15x - 18y = 9
--------------------
27x + 0y = 27
27x = 27
x = 27/27
x = 1
Reemplazo x = 1 en ecuación 2.
5x - 6y = 3
5 (1) - 6y = 3
5 - 6y = 3
-6y = 3 - 5
-6y = -2
y = -2/-6---sacamos la mitad
y = 1/3
Respuestas :
x = 1
y = 1/3
