Question

Resolver el siguien sistema de ecuaciones 3x3
x+y+z=8
2x-3y+2z=26
x-y-3z=-12

Answer 1

Respuesta:

x = 4, y = -2 z = 6

Explicación paso a paso:

x+y+z=8......(x-2)

2x-3y+2z=26(x1)

x-y-3z=-12(x-1)

-2x - 2y - 2z = -16 x + y + z = 8

2x - 3y + 2z = 26 -x + y + 3z = 12

-5y = 10 y = -2 2y + 4z = 20

2(-2) + 4z = 20 => 4z = 24 => z = 6

x + (-2) + 6 = 8

x = 4

RPTA: x = 4, y = -2, z = 6
