Whakaoti i te C=200x+400000/x

$$C = \frac { 200 x + 400000 } { x }$$

Whakaoti mō x

$$x=\frac{400000}{C-200}$$

$$C\neq 200$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.

$$Cx=200x+400000$$

Tangohia te 200x mai i ngā taha e rua.

$$Cx-200x=400000$$

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

$$\left(C-200\right)x=400000$$

Whakawehea ngā taha e rua ki te C-200.

$$\frac{\left(C-200\right)x}{C-200}=\frac{400000}{C-200}$$

Mā te whakawehe ki te C-200 ka wetekia te whakareanga ki te C-200.

$$x=\frac{400000}{C-200}$$

Tē taea kia ōrite te tāupe x ki 0.

$$x=\frac{400000}{C-200}\text{, }x\neq 0$$

Whakaoti mō C

$$C=200+\frac{400000}{x}$$

$$x\neq 0$$
