Whakaoti i te {l}{x+y=3}{y+z=-6}{z+x=-7}

$$\left\{ \begin{array} { l } { x + y = 3 } \\ { y + z = - 6 } \\ { z + x = - 7 } \end{array} \right.$$

Whakaoti mō x, y, z

$$x=1$$

$$y=2$$

$$z=-8$$

Ngā Hipanga Poto E Whakamahi Whakakapinga Ana

Me whakaoti te x+y=3 mō x.

$$x=-y+3$$

Whakakapia te -y+3 mō te x i te whārite z+x=-7.

$$z-y+3=-7$$

Me whakaoti te whārite tuarua mō y me te whārite tuatoru mō z.

$$y=-z-6 z=y-10$$

Whakakapia te -z-6 mō te y i te whārite z=y-10.

$$z=-z-6-10$$

Me whakaoti te z=-z-6-10 mō z.

$$z=-8$$

Whakakapia te -8 mō te z i te whārite y=-z-6.

$$y=-\left(-8\right)-6$$

Tātaitia te y i te y=-\left(-8\right)-6.

$$y=2$$

Whakakapia te 2 mō te y i te whārite x=-y+3.

$$x=-2+3$$

Tātaitia te x i te x=-2+3.

$$x=1$$

Kua oti te pūnaha te whakatau.

$$x=1 y=2 z=-8$$
