Whakaoti i te 6.65x+2.70y=806.1

$$6.65x+2.70y=806.1$$

Whakaoti mō x

$$x=\frac{16122-54y}{133}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 2.7y mai i ngā taha e rua.

$$6.65x=806.1-2.7y$$

He hanga arowhānui tō te whārite.

$$6.65x=\frac{8061-27y}{10}$$

Whakawehea ngā taha e rua o te whārite ki te 6.65, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{6.65x}{6.65}=\frac{8061-27y}{6.65\times 10}$$

Mā te whakawehe ki te 6.65 ka wetekia te whakareanga ki te 6.65.

$$x=\frac{8061-27y}{6.65\times 10}$$

Whakawehe \frac{8061-27y}{10} ki te 6.65 mā te whakarea \frac{8061-27y}{10} ki te tau huripoki o 6.65.

$$x=\frac{16122-54y}{133}$$

Whakaoti mō y

$$y=-\frac{133x}{54}+\frac{2687}{9}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 6.65x mai i ngā taha e rua.

$$2.7y=806.1-6.65x$$

He hanga arowhānui tō te whārite.

$$2.7y=-\frac{133x}{20}+806.1$$

Whakawehea ngā taha e rua o te whārite ki te 2.7, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{2.7y}{2.7}=\frac{-\frac{133x}{20}+806.1}{2.7}$$

Mā te whakawehe ki te 2.7 ka wetekia te whakareanga ki te 2.7.

$$y=\frac{-\frac{133x}{20}+806.1}{2.7}$$

Whakawehe 806.1-\frac{133x}{20} ki te 2.7 mā te whakarea 806.1-\frac{133x}{20} ki te tau huripoki o 2.7.

$$y=-\frac{133x}{54}+\frac{2687}{9}$$
