Sagot :
bonjour
A=5+(2x+3) = 5+2x+3 = 2x+8
B=5x-(3-4x) = 5x-3+4x=9x-3
D=-(-3x-1)+(x-3) = 3x+1+x-3 = 2x-2
E = -(8x+3)-4x= -8x-3-4x=-12x-3
F=8x-(5x+2)+(3-4x) = 8x-5x-2+3-4x= -x +1
C= (4x+2)+(-6x-2) = 4x+2-6x-2 = -2x
G=5x-6+(3-4x)-(-2x+8) = 5x-6+3-4x+2x-8 = 3x-11
Réponse :
bonjour
A = 5 + 2 x + 3 = 2 x + 8
B = 5 x - 3 + 4 x = 9 x - 3
D = - 3 x - 1 + x + 3 = - 2 x + 2
E = - 8 x - 3 - 4 x = - 12 x - 3
F = 8 x - 5 x - 2 + 3 - 4 x = - x + 1
C = 4 x + 2 - 6 x - 2 = - 2 x
G = 5 x - 6 + 3 - 4 x + 2 x - 8 = 3. x - 11
