Whakaoti i te 270=-5+x/2*3

$$270= \frac{ -5+x }{ 2 } \times 3$$

Whakaoti mō x

$$x=185$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 3.

$$\frac{270}{3}=\frac{-5+x}{2}$$

Whakawehea te 270 ki te 3, kia riro ko 90.

$$90=\frac{-5+x}{2}$$

Me whakarea ngā taha e rua ki te 2.

$$90\times 2=-5+x$$

Whakareatia te 90 ki te 2, ka 180.

$$180=-5+x$$

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

$$-5+x=180$$

Me tāpiri te 5 ki ngā taha e rua.

$$x=180+5$$

Tāpirihia te 180 ki te 5, ka 185.

$$x=185$$
