Whakaoti i te {r}{5y+10x=5}{4+2x=5}

$$\left\{ \begin{array} { r } { 5 y + 10 x = 5 } \\ { 4 + 2 x = 5 } \end{array} \right.$$

Whakaoti mō y, x

$$x=\frac{1}{2}=0.5$$

$$y=0$$

Ngā Upane Otinga

Whakaarohia te whārite tuarua. Tangohia te 4 mai i ngā taha e rua.

$$2x=5-4$$

Tangohia te 4 i te 5, ka 1.

$$2x=1$$

Whakawehea ngā taha e rua ki te 2.

$$x=\frac{1}{2}$$

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

$$5y+10\times \frac{1}{2}=5$$

Whakareatia te 10 ki te \frac{1}{2}, ka 5.

$$5y+5=5$$

Tangohia te 5 mai i ngā taha e rua.

$$5y=5-5$$

Tangohia te 5 i te 5, ka 0.

$$5y=0$$

Whakawehea ngā taha e rua ki te 5. Ko te kore i whakawehea ki te tau ehara te kore ka hua ko te kore.

$$y=0$$

Kua oti te pūnaha te whakatau.

$$y=0 x=\frac{1}{2}$$
