Réponse :
G = 3 x + 4 x
= 3 * x + 4 * x
= x + x + x + x + x + x + x
= 7 * x
= 7 x
H = 5 x + 2 x
= 5 * x + 2 * x
= x + x + x + x + x + x + x
= 7 * x
= 7 x
I = 2 x + 3 x + 4 x
= 2 * x + 3 * x + 4 * x
= x + x + x + x + x + x + x + x + x
= 9 * x
= 9 x
J = 3 x + x
= 3 * x + x
= x + x + x + x
= 4 * x
= 4 x
