Question
comment simplifier puis reduire les operations suivantes:
E=12x-3x
F=5b+7a-1,5b-7-a
G=4+6x*2y-6x+2y-xy-1
E=12x-3x
F=5b+7a-1,5b-7-a
G=4+6x*2y-6x+2y-xy-1

1. Réponse maudmarine
E = 12x - 3x
E = 9x
F= 5b + 7a - 1,5b - 7 - a
F = 5b - 1,5b + 7a - a - 7
F = 3,5b + 6a - 7
G = 4 + 6x * 2y - 6x + 2y - xy - 1
G = 4 + 12xy - 6x + 2y - xy - 1
G = 12xy - xy - 6x + 2y + 4 - 1
G = 11xy - 6x + 2y + 3 -
2. Réponse nonotata
E=12x-3x
e = 9x
F=5b+7a-1,5b-7-a
f = 7a-a +5b -1.5b -7
f = 6a +3.5b -7
G=4+6x*2y-6x+2y-xy-1
g = 4+ 12xy -6x+2y -xy -1
g = 12xy -xy -6x+2y +4-1
g = 11xy -6x +2y +3
