Whakaoti i te 2.69(1.57w-6.27)=0.87

$$2.69 ( 1.57 w - 6.27 ) = 0.87$$

Whakaoti mō w

$$w = \frac{177363}{42233} = 4\frac{8431}{42233} \approx 4.199630621$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 2.69.

$$1.57w-6.27=\frac{0.87}{2.69}$$

Whakarohaina te \frac{0.87}{2.69} mā te whakarea i te taurunga me te tauraro ki te 100.

$$1.57w-6.27=\frac{87}{269}$$

Me tāpiri te 6.27 ki ngā taha e rua.

$$1.57w=\frac{87}{269}+6.27$$

Me tahuri ki tau ā-ira 6.27 ki te hautau \frac{627}{100}.

$$1.57w=\frac{87}{269}+\frac{627}{100}$$

Ko te maha noa iti rawa atu o 269 me 100 ko 26900. Me tahuri \frac{87}{269} me \frac{627}{100} ki te hautau me te tautūnga 26900.

$$1.57w=\frac{8700}{26900}+\frac{168663}{26900}$$

Tā te mea he rite te tauraro o \frac{8700}{26900} me \frac{168663}{26900}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$1.57w=\frac{8700+168663}{26900}$$

Tāpirihia te 8700 ki te 168663, ka 177363.

$$1.57w=\frac{177363}{26900}$$

Whakawehea ngā taha e rua ki te 1.57.

$$w=\frac{\frac{177363}{26900}}{1.57}$$

Tuhia te \frac{\frac{177363}{26900}}{1.57} hei hautanga kotahi.

$$w=\frac{177363}{26900\times 1.57}$$

Whakareatia te 26900 ki te 1.57, ka 42233.

$$w=\frac{177363}{42233}$$
