Réponse :

A = 7 + x
B = 2x-1

C = 7-3x

E = 6x-1

F = 2+x

G = 6x+1
I = -4+2x

J = -11x-5

K = -x-8

Explications étape par étape :  

A = 9+(x-2)

A = 7 + x

B = 3x-(x+1)

B = 3x-x-1

B = 2x-1

C = 2+(5-3x)

C = 2+5-3x

C = 7-3x

E = 7x-(x+1)

E = 7x-x-1

E = 6x-1

F = 3-(-x+1)

F = 3+x-1

F = 2+x

G = 5x-(-1-x)

G = 5x+1+x

G = 6x+1

I = 2-(6-2x)

I = 2+2x-6

I = -4+2x

J = -7x+(-5-4x)

J = -7x-4x-5

J = -11x-5

K = 2x-(8+3x)

K = 2x-3x-8

K = -x-8
