bonjours, je suis en 4° et je n'arrive pas a résoudre le problème suivant :

fans de rap, Arnaud et Léa téléchargent des albums sur un site de musique spécialisé.
Sur ce site, tous les albums sont au même prix.
Léa dit à Arnaud: "j'ai téléchargé trois albums et il me reste 10,50euros."
Arnaud lui répond: "j'avais 73euros. j'ai téléchargé deux albums, il me reste la même somme que toi avant ton achat."

Quel est le prix d'un album?

voilà, merci
