Whakaoti i te {l}{y=4x+2}{y=10}

$$\left\{ \begin{array} { l } { y = 4 x + 2 } \\ { y = 10 } \end{array} \right.$$

Whakaoti mō y, x

$$x=2$$

$$y=10$$

Ngā Upane Otinga

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

$$10=4x+2$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$4x+2=10$$

Tangohia te 2 mai i ngā taha e rua.

$$4x=10-2$$

Tangohia te 2 i te 10, ka 8.

$$4x=8$$

Whakawehea ngā taha e rua ki te 4.

$$x=\frac{8}{4}$$

Whakawehea te 8 ki te 4, kia riro ko 2.

$$x=2$$

Kua oti te pūnaha te whakatau.

$$y=10 x=2$$
