Whakaoti i te {l}{3x+1=2}{x+y=1}

$$\left\{ \begin{array} { l } { 3 x + 1 = 2 } \\ { x + y = 1 } \end{array} \right.$$

Whakaoti mō x, y

$$x=\frac{1}{3}\approx 0.333333333$$

$$y=\frac{2}{3}\approx 0.666666667$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Tangohia te 1 mai i ngā taha e rua.

$$3x=2-1$$

Tangohia te 1 i te 2, ka 1.

$$3x=1$$

Whakawehea ngā taha e rua ki te 3.

$$x=\frac{1}{3}$$

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

$$\frac{1}{3}+y=1$$

Tangohia te \frac{1}{3} mai i ngā taha e rua.

$$y=1-\frac{1}{3}$$

Tangohia te \frac{1}{3} i te 1, ka \frac{2}{3}.

$$y=\frac{2}{3}$$

Kua oti te pūnaha te whakatau.

$$x=\frac{1}{3} y=\frac{2}{3}$$
