Whakaoti i te 1.5*3+6*3=4.5*x

$$1.5 \times 3+6 \times 3=4.5 \times x$$

Whakaoti mō x

$$x=5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 1.5 ki te 3, ka 4.5.

$$4.5+6\times 3=4.5x$$

Whakareatia te 6 ki te 3, ka 18.

$$4.5+18=4.5x$$

Tāpirihia te 4.5 ki te 18, ka 22.5.

$$22.5=4.5x$$

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

$$4.5x=22.5$$

Whakawehea ngā taha e rua ki te 4.5.

$$x=\frac{22.5}{4.5}$$

Whakarohaina te \frac{22.5}{4.5} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{225}{45}$$

Whakawehea te 225 ki te 45, kia riro ko 5.

$$x=5$$
