Whakaoti i te {r}{10x+14=460}{x+y=40}

$$\left. \begin{array} { r } { 10 x + 14 = 460 } \\ { x + y = 40 } \end{array} \right.$$

Whakaoti mō x, y

$$x = \frac{223}{5} = 44\frac{3}{5} = 44.6$$

$$y = -\frac{23}{5} = -4\frac{3}{5} = -4.6$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Tangohia te 14 mai i ngā taha e rua.

$$10x=460-14$$

Tangohia te 14 i te 460, ka 446.

$$10x=446$$

Whakawehea ngā taha e rua ki te 10.

$$x=\frac{446}{10}$$

Whakahekea te hautanga \frac{446}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=\frac{223}{5}$$

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

$$\frac{223}{5}+y=40$$

Tangohia te \frac{223}{5} mai i ngā taha e rua.

$$y=40-\frac{223}{5}$$

Tangohia te \frac{223}{5} i te 40, ka -\frac{23}{5}.

$$y=-\frac{23}{5}$$

Kua oti te pūnaha te whakatau.

$$x=\frac{223}{5} y=-\frac{23}{5}$$
