Whakaoti i te 139=x/831(334-299/299*334)

$$139 = \frac { x } { 831 } ( \frac { 334 - 299 } { 299 \times 334 } )$$

Whakaoti mō x

$$x = \frac{11535421794}{35} = 329583479\frac{29}{35} \approx 329583479.828571429$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia ngā taha e rua o te whārite ki te 831.

$$115509=x\times \frac{334-299}{299\times 334}$$

Tangohia te 299 i te 334, ka 35.

$$115509=x\times \frac{35}{299\times 334}$$

Whakareatia te 299 ki te 334, ka 99866.

$$115509=x\times \frac{35}{99866}$$

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

$$x\times \frac{35}{99866}=115509$$

Me whakarea ngā taha e rua ki te \frac{99866}{35}, te tau utu o \frac{35}{99866}.

$$x=115509\times \frac{99866}{35}$$

Tuhia te 115509\times \frac{99866}{35} hei hautanga kotahi.

$$x=\frac{115509\times 99866}{35}$$

Whakareatia te 115509 ki te 99866, ka 11535421794.

$$x=\frac{11535421794}{35}$$
