Whakaoti i te {l}{x+x+x=60}{x+y=30}{x+z=3}

$$\left\{ \begin{array} { l } { x + x + x = 60 } \\ { x + y = 30 } \\ { x + z = 3 } \end{array} \right.$$

Whakaoti mō x, y, z

$$x=20$$

$$y=10$$

$$z=-17$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Pahekotia te x me x, ka 2x.

$$2x+x=60$$

Pahekotia te 2x me x, ka 3x.

$$3x=60$$

Whakawehea ngā taha e rua ki te 3.

$$x=\frac{60}{3}$$

Whakawehea te 60 ki te 3, kia riro ko 20.

$$x=20$$

Whakaarohia te whārite tuarua. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$20+y=30$$

Tangohia te 20 mai i ngā taha e rua.

$$y=30-20$$

Tangohia te 20 i te 30, ka 10.

$$y=10$$

Whakaarohia te whārite tuatoru. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$20+z=3$$

Tangohia te 20 mai i ngā taha e rua.

$$z=3-20$$

Tangohia te 20 i te 3, ka -17.

$$z=-17$$

Kua oti te pūnaha te whakatau.

$$x=20 y=10 z=-17$$
