Amigos me ajudeeeeem!!! Tema:
x-y+1090-x+z-y+300-z-y-x=800+450-z-y+578-z+803-z+y+x-560
Obrigado
PS:minha sora é mei doida

Answer 1

$x-y+1~090-x+z-y+300-z-y-x=800+450-z-y+578-z+803-z+y+x-560$

$(x-x)+(1~090+300)+(z-z)+(-y-y)=(800+450+578+803-560)+(-z-z)+(-y+y)+x$

$1~390-2y=2~071-2z+x$

$2z-2y-x=2~071-1~390$

$\boxed{2z-2y-x=681}$

Answer 2

X-Y+1090-X+Z-Y+300-Z-Y-X = 800+450-Z-Y+578-Z+803-Z+Y+X-560

X-Y+1090-X+Z-X + 2Y +2 + 300 = 800+450-Z-Y+578-Z+X + Y - 243

X-Y+1090- 2X - 2Y + 300 = 800+450-Z-Y +X + Y -2 Z + 821

-X -3Y - 1390 = X - 3Z - 2071

-X - 3Y - 1390 - X .+ 3Z + 2071

-2X - 3Y - 3Z + 681 =0
