Whakaoti i te 220(x+100)=330

$$220 ( x + 100 ) = 330$$

Whakaoti mō x

$$x = -\frac{197}{2} = -98\frac{1}{2} = -98.5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea ngā taha e rua ki te 220.

$$x+100=\frac{330}{220}$$

Whakahekea te hautanga \frac{330}{220} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 110.

$$x+100=\frac{3}{2}$$

Tangohia te 100 mai i ngā taha e rua.

$$x=\frac{3}{2}-100$$

Me tahuri te 100 ki te hautau \frac{200}{2}.

$$x=\frac{3}{2}-\frac{200}{2}$$

Tā te mea he rite te tauraro o \frac{3}{2} me \frac{200}{2}, me tango rāua mā te tango i ō raua taurunga.

$$x=\frac{3-200}{2}$$

Tangohia te 200 i te 3, ka -197.

$$x=-\frac{197}{2}$$
