Question

Ecuacion de cualquier metodox + y – z = 32x – 3y + z = 2x + y + z = 4

Answer 1

x + y - z = 4
32x - 3y + z = 4
2x + y + z = 4

z = 4 + x + y

32x - 3y + 4 + x + y = 4
33x - 2y = 0
y = (33/2)x

2x + (33/2)x + 4 + x + (33/2)x = 4
3x + 33x = 0
36x = 0
x = 0

y = (33/2)(0)
y = 0

z = 4 + 0 + 0
z = 4


Entonces

(x,y,z) = (0,0,4)
