Bonjour :)
Je n'arrive pas à résoudre le système d'équations suivant :
−16x + 31y = 256
x − 2y = 75
Merci d'avance

Résoudre le système d’équation
−16x + 31y = 256
x − 2y = 75
x=75+2y
−16x + 31y = 256
-16(75+2y)+31y=256
-1 200 - 32y +31y =256
y=-1456
x=75+2y
x=75+2(-1456)
x=-2 837 S={(-2 837; -1 456)}
