Whakaoti i te y=1-2x/1+x

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

Whakaoti mō x

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

$$y\neq -2$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki -1 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x+1.

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

Whakamahia te āhuatanga tohatoha hei whakarea te y ki te x+1.

$$yx+y=1-2x$$

Me tāpiri te 2x ki ngā taha e rua.

$$yx+y+2x=1$$

Tangohia te y mai i ngā taha e rua.

$$yx+2x=1-y$$

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

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

Whakawehea ngā taha e rua ki te y+2.

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

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

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

Tē taea kia ōrite te tāupe x ki -1.

$$x=\frac{1-y}{y+2}\text{, }x\neq -1$$

Whakaoti mō y

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

$$x\neq -1$$
