Whakaoti i te 72x-36/70=75

$$72 x - \frac { 36 } { 70 } = 75$$

Whakaoti mō x

$$x = \frac{881}{840} = 1\frac{41}{840} \approx 1.048809524$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakahekea te hautanga \frac{36}{70} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$72x-\frac{18}{35}=75$$

Me tāpiri te \frac{18}{35} ki ngā taha e rua.

$$72x=75+\frac{18}{35}$$

Me tahuri te 75 ki te hautau \frac{2625}{35}.

$$72x=\frac{2625}{35}+\frac{18}{35}$$

Tā te mea he rite te tauraro o \frac{2625}{35} me \frac{18}{35}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$72x=\frac{2625+18}{35}$$

Tāpirihia te 2625 ki te 18, ka 2643.

$$72x=\frac{2643}{35}$$

Whakawehea ngā taha e rua ki te 72.

$$x=\frac{\frac{2643}{35}}{72}$$

Tuhia te \frac{\frac{2643}{35}}{72} hei hautanga kotahi.

$$x=\frac{2643}{35\times 72}$$

Whakareatia te 35 ki te 72, ka 2520.

$$x=\frac{2643}{2520}$$

Whakahekea te hautanga \frac{2643}{2520} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$x=\frac{881}{840}$$
