Whakaoti i te 0.3x+0.1y=3

$$0.3 x + 0.1 y = 3$$

Whakaoti mō x

$$x=-\frac{y}{3}+10$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 0.1y mai i ngā taha e rua.

$$0.3x=3-0.1y$$

He hanga arowhānui tō te whārite.

$$0.3x=-\frac{y}{10}+3$$

Whakawehea ngā taha e rua o te whārite ki te 0.3, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{0.3x}{0.3}=\frac{-\frac{y}{10}+3}{0.3}$$

Mā te whakawehe ki te 0.3 ka wetekia te whakareanga ki te 0.3.

$$x=\frac{-\frac{y}{10}+3}{0.3}$$

Whakawehe 3-\frac{y}{10} ki te 0.3 mā te whakarea 3-\frac{y}{10} ki te tau huripoki o 0.3.

$$x=-\frac{y}{3}+10$$

Whakaoti mō y

$$y=30-3x$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 0.3x mai i ngā taha e rua.

$$0.1y=3-0.3x$$

He hanga arowhānui tō te whārite.

$$0.1y=-\frac{3x}{10}+3$$

Me whakarea ngā taha e rua ki te 10.

$$\frac{0.1y}{0.1}=\frac{-\frac{3x}{10}+3}{0.1}$$

Mā te whakawehe ki te 0.1 ka wetekia te whakareanga ki te 0.1.

$$y=\frac{-\frac{3x}{10}+3}{0.1}$$

Whakawehe 3-\frac{3x}{10} ki te 0.1 mā te whakarea 3-\frac{3x}{10} ki te tau huripoki o 0.1.

$$y=30-3x$$
