Whakaoti i te y=7-2x/3

$$y = \frac { 7 - 2 x } { 3 }$$

Whakaoti mō x

$$x=\frac{7-3y}{2}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ia wā o 7-2x ki te 3, kia riro ko \frac{7}{3}-\frac{2}{3}x.

$$y=\frac{7}{3}-\frac{2}{3}x$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$\frac{7}{3}-\frac{2}{3}x=y$$

Tangohia te \frac{7}{3} mai i ngā taha e rua.

$$-\frac{2}{3}x=y-\frac{7}{3}$$

Whakawehea ngā taha e rua o te whārite ki te -\frac{2}{3}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{-\frac{2}{3}x}{-\frac{2}{3}}=\frac{y-\frac{7}{3}}{-\frac{2}{3}}$$

Mā te whakawehe ki te -\frac{2}{3} ka wetekia te whakareanga ki te -\frac{2}{3}.

$$x=\frac{y-\frac{7}{3}}{-\frac{2}{3}}$$

Whakawehe y-\frac{7}{3} ki te -\frac{2}{3} mā te whakarea y-\frac{7}{3} ki te tau huripoki o -\frac{2}{3}.

$$x=\frac{7-3y}{2}$$

Whakaoti mō y

$$y=\frac{7-2x}{3}$$

Ngā Upane Otinga

Whakawehea ia wā o 7-2x ki te 3, kia riro ko \frac{7}{3}-\frac{2}{3}x.

$$y=\frac{7}{3}-\frac{2}{3}x$$
