y = higos
Panteamos las ecuaciones,
2x + 3y = 13....(1)
3x + 2y = 12....(2)
Resolvemos,
x=13-3y/2........(1)
x=12-2y/3........(2)
13-3y/2=12-2y/3
39-9y=24-4y
-9y+4y=24-39
-5y=-15
y=3
x=13-3(3)/2
x=13-9/2
x=4/2
x=2
Respuesta: el kilo de albaricoque cuesta € 2, y el de higo cuesta € 3.
Espero que te sirva, Saludos!!
