Whakaoti i te 4=260000/frac{x+x+20000{2}}

$$4 = \frac { 260000 } { \frac { x + x + 20000 } { 2 } }$$

Whakaoti mō x

$$x=55000$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehe 260000 ki te \frac{x+x+20000}{2} mā te whakarea 260000 ki te tau huripoki o \frac{x+x+20000}{2}.

$$4=\frac{260000\times 2}{x+x+20000}$$

Whakareatia te 260000 ki te 2, ka 520000.

$$4=\frac{520000}{x+x+20000}$$

Pahekotia te x me x, ka 2x.

$$4=\frac{520000}{2x+20000}$$

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

$$\frac{520000}{2x+20000}=4$$

Tē taea kia ōrite te tāupe x ki -10000 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te 2\left(x+10000\right).

$$520000=8\left(x+10000\right)$$

Whakawehea ngā taha e rua ki te 8.

$$\frac{520000}{8}=x+10000$$

Whakawehea te 520000 ki te 8, kia riro ko 65000.

$$65000=x+10000$$

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

$$x+10000=65000$$

Tangohia te 10000 mai i ngā taha e rua.

$$x=65000-10000$$

Tangohia te 10000 i te 65000, ka 55000.

$$x=55000$$
