Developpe et reduis les expressions : E = 11 + 2(x-6) F = -3 (2y-4) - 2y G = 7 - 4(8-2a) + a

E = 11 + 2(x - 6)
E = 11 + 2x - 12
E = 2x - 1

F = -3(2y - 4) - 2y
F = -6y + 12 - 2y
F = -8y + 12

G = 7 - 4(8 - 2a) + a
G = 7 - 32 + 8a + a
G = 9a - 25

E= 11 + 2(x-6)
E= 11 +2x -12
E= 2x -1

F= -3(2y-4) -2y
F= -6y +12 -2y
F= -8y +12

G= 7 -4(8-2a) +a
G= 7 -32 +8a +a
G= 9a -25
