Whakaoti i te y+4=2/5(x-3)

$$y + 4 = \frac { 2 } { 5 } ( x - 3 )$$

Whakaoti mō x

$$x=\frac{5y}{2}+13$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te \frac{2}{5} ki te x-3.

$$y+4=\frac{2}{5}x-\frac{6}{5}$$

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

$$\frac{2}{5}x-\frac{6}{5}=y+4$$

Me tāpiri te \frac{6}{5} ki ngā taha e rua.

$$\frac{2}{5}x=y+4+\frac{6}{5}$$

Tāpirihia te 4 ki te \frac{6}{5}, ka \frac{26}{5}.

$$\frac{2}{5}x=y+\frac{26}{5}$$

Whakawehea ngā taha e rua o te whārite ki te \frac{2}{5}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{\frac{2}{5}x}{\frac{2}{5}}=\frac{y+\frac{26}{5}}{\frac{2}{5}}$$

Mā te whakawehe ki te \frac{2}{5} ka wetekia te whakareanga ki te \frac{2}{5}.

$$x=\frac{y+\frac{26}{5}}{\frac{2}{5}}$$

Whakawehe y+\frac{26}{5} ki te \frac{2}{5} mā te whakarea y+\frac{26}{5} ki te tau huripoki o \frac{2}{5}.

$$x=\frac{5y}{2}+13$$

Whakaoti mō y

$$y=\frac{2\left(x-13\right)}{5}$$

Ngā Upane Otinga

Whakamahia te āhuatanga tohatoha hei whakarea te \frac{2}{5} ki te x-3.

$$y+4=\frac{2}{5}x-\frac{6}{5}$$

Tangohia te 4 mai i ngā taha e rua.

$$y=\frac{2}{5}x-\frac{6}{5}-4$$

Tangohia te 4 i te -\frac{6}{5}, ka -\frac{26}{5}.

$$y=\frac{2}{5}x-\frac{26}{5}$$
