Equations à deux inconnus
Par Marie M.

Imaginons :
x + 2y = 6
y - x = 2
QUE FAISONS NOUS ?
3
Donc...
Comme y est égal à x + 2, on va le remplacer dans l'équation
x + 2(x+2) = 6
Donc 3 x + 4 = 6
Donc 3x = 2
Donc x = 3 demis = 1.5
Et par conséquent, y = 3.5
4
Eh bien quoi ? C'était dur ?
Pour vous entrainer, voici un autre système :
x + 4 y = 12
y - x = 5
BONNE CHANCE A TOUS !!!
