G = 5x-2 J = 2(-y+5)
H = 2(-3t+7) K = 10z-13
I = -3(4a+1) L = -2x-5
Explications étape par étape :
G = (x+3)+(4x-5) J = (3y+7)+(-5y+3)
G = x+3+4x-5 J = 3y+7-5y+3
G = x+4x+3-5 J = 3y-5y+7+3
G = (1+4)x+(3-5) J = (3-5)y+(7+3)
G = 5x+(-2) J = -2y+10
G = 5x-2 J = 2*(-y)+2*5
J = 2(-y+5)
H = 6-2t-(4t-8) K = 5z-6-(7-2z)+3z
H = 6-2t-4t+8 K = 5z-6-7-(-2z)+3z
H = -2t-4t+6+8 K = 5z-6-7+2z+3z
H = (-2-4)t+(6+8) K = (5+2+3)z+(-6-7)
H = -6t+14 K = 10z-13
H = 2*(-3)t+2*7
H = 2(-3t+7)
I = -(8a+3)-4a L = (3-4x)-(-2x+8)
I = -8a-3-4a L = 3-4x-(-2x)-8
I = -8a-4a-3 L = 3-4x+2x-8
I = (-8-4)a-3 L = -4x+2x+3-8
I = -12a-3 L = (-4+2)x+(3-8)
I = -3*4a-3*1 L = -2x-5
I = -3(4a+1)
