Whakaoti i te {l}{4x+2=8}{2x+y=x/8}

$$\left. \begin{array} { l } { 4 x + 2 = 8 } \\ { 2 x + y = \frac { x } { 8 } } \end{array} \right.$$

Whakaoti mō x, y

$$x = \frac{3}{2} = 1\frac{1}{2} = 1.5$$

$$y = -\frac{45}{16} = -2\frac{13}{16} = -2.8125$$

Ngā Upane Otinga

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

$$4x=8-2$$

Tangohia te 2 i te 8, ka 6.

$$4x=6$$

Whakawehea ngā taha e rua ki te 4.

$$x=\frac{6}{4}$$

Whakahekea te hautanga \frac{6}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

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

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

$$2\times \frac{3}{2}+y=\frac{\frac{3}{2}}{8}$$

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

$$3+y=\frac{\frac{3}{2}}{8}$$

Tuhia te \frac{\frac{3}{2}}{8} hei hautanga kotahi.

$$3+y=\frac{3}{2\times 8}$$

Whakareatia te 2 ki te 8, ka 16.

$$3+y=\frac{3}{16}$$

Tangohia te 3 mai i ngā taha e rua.

$$y=\frac{3}{16}-3$$

Tangohia te 3 i te \frac{3}{16}, ka -\frac{45}{16}.

$$y=-\frac{45}{16}$$

Kua oti te pūnaha te whakatau.

$$x=\frac{3}{2} y=-\frac{45}{16}$$
