Whakaoti i te {cc}{x}&{y}{2}&{4}{l}{6}{x}={r}{-2}{4}

$$\left( \begin{array} { c c } { x } & { y } \\ { 2 } & { 4 } \end{array} \right) \left( \begin{array} { l } { 6 } \\ { x } \end{array} \right) = \left( \begin{array} { r } { - 2 } \\ { 4 } \end{array} \right)$$

Whakaoti mō x, y

$$x=-2$$

$$y=-5$$

Ngā Upane Otinga

Whakaarohia te whārite tuarua. Tangohia te 12 mai i ngā taha e rua.

$$4x=4-12$$

Tangohia te 12 i te 4, ka -8.

$$4x=-8$$

Whakawehea ngā taha e rua ki te 4.

$$x=\frac{-8}{4}$$

Whakawehea te -8 ki te 4, kia riro ko -2.

$$x=-2$$

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

$$6\left(-2\right)+y\left(-2\right)=-2$$

Whakareatia te 6 ki te -2, ka -12.

$$-12+y\left(-2\right)=-2$$

Me tāpiri te 12 ki ngā taha e rua.

$$y\left(-2\right)=-2+12$$

Tāpirihia te -2 ki te 12, ka 10.

$$y\left(-2\right)=10$$

Whakawehea ngā taha e rua ki te -2.

$$y=\frac{10}{-2}$$

Whakawehea te 10 ki te -2, kia riro ko -5.

$$y=-5$$

Kua oti te pūnaha te whakatau.

$$x=-2 y=-5$$
