Whakaoti i te {l}{2x+6=6}{4x+3y=74}

$$\left. \begin{array} { l } { 2 x + 6 = 6 } \\ { 4 x + 3 y = 74 } \end{array} \right.$$

Whakaoti mō x, y

$$x=0$$

$$y = \frac{74}{3} = 24\frac{2}{3} \approx 24.666666667$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Tangohia te 6 mai i ngā taha e rua.

$$2x=6-6$$

Tangohia te 6 i te 6, ka 0.

$$2x=0$$

Whakawehea ngā taha e rua ki te 2. Ko te kore i whakawehea ki te tau ehara te kore ka hua ko te kore.

$$x=0$$

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

$$4\times 0+3y=74$$

Whakareatia te 4 ki te 0, ka 0.

$$0+3y=74$$

Ko te tau i tāpiria he kore ka hua koia tonu.

$$3y=74$$

Whakawehea ngā taha e rua ki te 3.

$$y=\frac{74}{3}$$

Kua oti te pūnaha te whakatau.

$$x=0 y=\frac{74}{3}$$
