  • distribution de 50 billes entre Luis, Christopher et Wilfried

    Christopher = Luis x2

    Wilfried = Christopher + 5 = (Luis x 2) +5

    ( 2 Luis + 5) + 2 Luis + Luis = 50 billes => 5 Luis + 5 = 50 billes = 5 Luis = -5 + 50 billes => 5 Luis = 45 billes => Luis = 45/5 = 9 billes

    Christopher = 2 Luis = 9 x 2 = 18 billes

    Wilfried = Christopher + 5 = 18 + 5 = 23 billes

    vérification : 9 + 18 + 23 = 50

  • Luis a x billes
    Christopher a 2x
    Wilfred a  2x+5

    x+2x+2x+5 = 50
    5x+5 = 20
    5x =50-5
    5x = 45
    x = 9

    luis a 9billes
    Christopher a 18 billes
    Wilfrid a 23 billes
