Whakaoti i te {l}{2x+y=0}{3x+2=1}

$$\left. \begin{array} { l } { 2 x + y = 0 } \\ { 3 x + 2 = 1 } \end{array} \right.$$

Whakaoti mō x, y

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

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

Ngā Upane Otinga

Whakaarohia te whārite tuarua. Tangohia te 2 mai i ngā taha e rua.

$$3x=1-2$$

Tangohia te 2 i te 1, ka -1.

$$3x=-1$$

Whakawehea ngā taha e rua ki te 3.

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

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

$$2\left(-\frac{1}{3}\right)+y=0$$

Whakareatia te 2 ki te -\frac{1}{3}, ka -\frac{2}{3}.

$$-\frac{2}{3}+y=0$$

Me tāpiri te \frac{2}{3} ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

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

Kua oti te pūnaha te whakatau.

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