Whakaoti i te {l}{x+5y=0}{15y=-3}

$$\left. \begin{array} { l } { x + 5 y = 0 } \\ { 15 y = - 3 } \end{array} \right.$$

Whakaoti mō x, y

$$x=1$$

$$y=-\frac{1}{5}=-0.2$$

Ngā Upane Otinga

Whakaarohia te whārite tuarua. Whakawehea ngā taha e rua ki te 15.

$$y=\frac{-3}{15}$$

Whakahekea te hautanga \frac{-3}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$y=-\frac{1}{5}$$

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

$$x+5\left(-\frac{1}{5}\right)=0$$

Whakareatia te 5 ki te -\frac{1}{5}, ka -1.

$$x-1=0$$

Me tāpiri te 1 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$x=1$$

Kua oti te pūnaha te whakatau.

$$x=1 y=-\frac{1}{5}$$
