Whakaoti i te xy-3x+2y=1

$$xy-3x+2y=1$$

Whakaoti mō x

$$x=-\frac{2y-1}{y-3}$$

$$y\neq 3$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 2y mai i ngā taha e rua.

$$xy-3x=1-2y$$

Pahekotia ngā kīanga tau katoa e whai ana i te x.

$$\left(y-3\right)x=1-2y$$

Whakawehea ngā taha e rua ki te y-3.

$$\frac{\left(y-3\right)x}{y-3}=\frac{1-2y}{y-3}$$

Mā te whakawehe ki te y-3 ka wetekia te whakareanga ki te y-3.

$$x=\frac{1-2y}{y-3}$$

Whakaoti mō y

$$y=\frac{3x+1}{x+2}$$

$$x\neq -2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me tāpiri te 3x ki ngā taha e rua.

$$xy+2y=1+3x$$

Pahekotia ngā kīanga tau katoa e whai ana i te y.

$$\left(x+2\right)y=1+3x$$

He hanga arowhānui tō te whārite.

$$\left(x+2\right)y=3x+1$$

Whakawehea ngā taha e rua ki te x+2.

$$\frac{\left(x+2\right)y}{x+2}=\frac{3x+1}{x+2}$$

Mā te whakawehe ki te x+2 ka wetekia te whakareanga ki te x+2.

$$y=\frac{3x+1}{x+2}$$
