Une histoire de petites bêtes

Une histoire de petites bêtes :

Olivia va dans la forêt. Elle revient avec des araignées et des fourmis dans une boîte.

Il y a en tout 27 petites bêtes et 190 pattes dans la boîte.

Combien y a-t-il d’araignées et de fourmis ?

Il y a 13 fourmis et 14 araignées.

Le nombre total de fourmis et d’araignées est de 27. Une fourmi a 6 pattes, une araignée a 8 pattes et le nombre total de pattes est de 190. Cela revient à résoudre le sytème : F+A =27 et Fx6+Ax8 =190 (avec F et A représentant respectivement le nombre de fourmis et d’araignées).
