Bonsoir pouvez vous m'aider pour l'exercice 3 s'il vous plaît ? Le + vite possible Merci d'avance

bonjour

A = 10 x

B = 5 x + 11

C = 6 x + 8

D =   2 x + 6 + 5 x = 7 x + 6

E = 15 x + 10 + 5 x = 20 x + 10

F = 3 x + 12 + x + 6 + 2 x = 6 x + 18

G = 4 x + 8 + 6 x + 30 = 10 x + 38

Bonsoir,

A = 6x + x + 3x

A = 10x

B = 5 + 3x + 6 + 2x

B = 3x + 2x + 5 + 6

B = 5x + 11

C = 2x + 3 + x + 3x + 5

C = 2x + x + 3x + 3 + 5

C = 6x + 8

D = 2 * (x + 3) + 5x

D = 2x + 6 + 5x

D = 2x + 5x + 6

D =  7x + 6

E = 15x + 5 * (2 + x)

E = 15x + 10 + 5x

E = 15x + 5x + 10

E = 20x + 10

F = 3 * (x + 4) + x + 2 * (3 + x)

F = 3x + 12 + x + 6 + 2x

F = 3x + x + 2x + 12 + 6

F = 6x + 18

G = 4 * (x + 2) + 6 * (x + 5)

G = 4x + 8 + 6x + 30

G = 4x + 6x + 8 + 30

G = 10x + 38.
