Whakaoti i te {l}{15x+y=0}{16y=-3}

$$\left\{ \begin{array} { l } { 15 x + y = 0 } \\ { 16 y = - 3 } \end{array} \right.$$

Whakaoti mō x, y

$$x=\frac{1}{80}=0.0125$$

$$y=-\frac{3}{16}=-0.1875$$

Ngā Upane Otinga

Whakaarohia te whārite tuarua. Whakawehea ngā taha e rua ki te 16.

$$y=-\frac{3}{16}$$

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

$$15x-\frac{3}{16}=0$$

Me tāpiri te \frac{3}{16} ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$15x=\frac{3}{16}$$

Whakawehea ngā taha e rua ki te 15.

$$x=\frac{\frac{3}{16}}{15}$$

Tuhia te \frac{\frac{3}{16}}{15} hei hautanga kotahi.

$$x=\frac{3}{16\times 15}$$

Whakareatia te 16 ki te 15, ka 240.

$$x=\frac{3}{240}$$

Whakahekea te hautanga \frac{3}{240} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$x=\frac{1}{80}$$

Kua oti te pūnaha te whakatau.

$$x=\frac{1}{80} y=-\frac{3}{16}$$
