Whakaoti i te 106.6*(9-2x)=54

$$106.6 \cdot ( 9 - 2 x ) = 54$$

Whakaoti mō x

$$x = \frac{4527}{1066} = 4\frac{263}{1066} \approx 4.246716698$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 106.6.

$$9-2x=\frac{54}{106.6}$$

Whakarohaina te \frac{54}{106.6} mā te whakarea i te taurunga me te tauraro ki te 10.

$$9-2x=\frac{540}{1066}$$

Whakahekea te hautanga \frac{540}{1066} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$9-2x=\frac{270}{533}$$

Tangohia te 9 mai i ngā taha e rua.

$$-2x=\frac{270}{533}-9$$

Me tahuri te 9 ki te hautau \frac{4797}{533}.

$$-2x=\frac{270}{533}-\frac{4797}{533}$$

Tā te mea he rite te tauraro o \frac{270}{533} me \frac{4797}{533}, me tango rāua mā te tango i ō raua taurunga.

$$-2x=\frac{270-4797}{533}$$

Tangohia te 4797 i te 270, ka -4527.

$$-2x=-\frac{4527}{533}$$

Whakawehea ngā taha e rua ki te -2.

$$x=\frac{-\frac{4527}{533}}{-2}$$

Tuhia te \frac{-\frac{4527}{533}}{-2} hei hautanga kotahi.

$$x=\frac{-4527}{533\left(-2\right)}$$

Whakareatia te 533 ki te -2, ka -1066.

$$x=\frac{-4527}{-1066}$$

Ka taea te hautanga \frac{-4527}{-1066} te whakamāmā ki te \frac{4527}{1066} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$x=\frac{4527}{1066}$$
