Question

9x+4y-10z=6

6x-8y+5z=-1

12x+12y-15z=10

Answer 1

Respuesta:

x = 1/3 y = 1/4 z = -1/5

Explicación:

9x+4y-10z=6(x-2)(x-4).......(1)

6x-8y+5z=-1(x3)..........(2)

12x+12y-15z=10(x3).......(3)

-18x - 8y + 20z = -12 -36x - 16y + 40z = -24

18x - 24y + 15z = -3 36x + 36y - 45z = 30

-32y + 35z = -15 20y - 5z = 6

-32y + 35z = -15(x5)....(4) -160y + 175z = -75

20y - 5z = 6(x8).....(5) 160y - 40z = 48

135z = -27 z = -1/5 y = 1/4 x = 1/3

RPTA: x = 1/3 y = 1/4 z = -1/5
