Whakaoti i te y=7/2x-2

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

Whakaoti mō x

$$x=\frac{2\left(y+2\right)}{7}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

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

Me tāpiri te 2 ki ngā taha e rua.

$$\frac{7}{2}x=y+2$$

Whakawehea ngā taha e rua o te whārite ki te \frac{7}{2}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{\frac{7}{2}x}{\frac{7}{2}}=\frac{y+2}{\frac{7}{2}}$$

Mā te whakawehe ki te \frac{7}{2} ka wetekia te whakareanga ki te \frac{7}{2}.

$$x=\frac{y+2}{\frac{7}{2}}$$

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

$$x=\frac{2y+4}{7}$$

Whakaoti mō y

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