Bonjour

Résoudre le système d’équations suivant :

2y - x = 6

4y-10x+4=0

2y - x = 6

4y - 10x = - 4

- 4y + 2x = - 12

4y - 10x = - 4

+ 2x - 10x = - 12 - 4

- 8x = - 16

x = 16/8

x = 2

2y - x = 6

2y - 2 = 6

2y = 6 + 2

2y = 8

y = 8/2

y = 4

S = (2 ; 4)

bonjour

2 y - x =  6

4 y - 10 x = - 4

- 4 y + 2 x = - 12

4 y -  10 x = - 4

- 8 x =  - 16

x =  2

2 y - 2 = 6

2 y =  8

y  = 4

x = 2 et  y = 4
