Whakaoti i te y=(25000+0.42x)div(x-50)

$$y=(25000+0.42x) \div (x-50)$$

Whakaoti mō x

$$x=\frac{2500\left(y+500\right)}{50y-21}$$

$$y\neq \frac{21}{50}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki 50 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x-50.

$$y\left(x-50\right)=25000+0.42x$$

Whakamahia te āhuatanga tohatoha hei whakarea te y ki te x-50.

$$yx-50y=25000+0.42x$$

Tangohia te 0.42x mai i ngā taha e rua.

$$yx-50y-0.42x=25000$$

Me tāpiri te 50y ki ngā taha e rua.

$$yx-0.42x=25000+50y$$

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

$$\left(y-0.42\right)x=25000+50y$$

He hanga arowhānui tō te whārite.

$$\left(y-\frac{21}{50}\right)x=50y+25000$$

Whakawehea ngā taha e rua ki te y-\frac{21}{50}.

$$\frac{\left(y-\frac{21}{50}\right)x}{y-\frac{21}{50}}=\frac{50y+25000}{y-\frac{21}{50}}$$

Mā te whakawehe ki te y-\frac{21}{50} ka wetekia te whakareanga ki te y-\frac{21}{50}.

$$x=\frac{50y+25000}{y-\frac{21}{50}}$$

Whakawehe 25000+50y ki te y-\frac{21}{50}.

$$x=\frac{2500\left(y+500\right)}{50y-21}$$

Tē taea kia ōrite te tāupe x ki 50.

$$x=\frac{2500\left(y+500\right)}{50y-21}\text{, }x\neq 50$$

Whakaoti mō y

$$y=\frac{21x+1250000}{50\left(x-50\right)}$$

$$x\neq 50$$
