Dado que los precios de los artículos están en la razón 3:4, establecemos una ecuación para representar esta relación: \frac{x}{y} = \frac{3}{4}. Reescribimos esta ecuación como y = \frac{4}{3}x y la sustituimos en la expresión de la diferencia de los precios y - x = 1800. Esto produce \frac{4}{3}x - x = 1800, que simplificamos a \frac{1}{3}x = 1800. Al despejar para x, encontramos x = 5400. Luego sustituimos este valor en la ecuación para y para descubrir que y = 7200. Así, los precios de los dos artículos son 5400 y 7200.
