Whakaoti i te 3(r+2s)=2t-4

$$3(r+2s)=2t-4$$

Whakaoti mō r

$$r=\frac{2\left(-3s+t-2\right)}{3}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te r+2s.

$$3r+6s=2t-4$$

Tangohia te 6s mai i ngā taha e rua.

$$3r=2t-4-6s$$

He hanga arowhānui tō te whārite.

$$3r=-6s+2t-4$$

Whakawehea ngā taha e rua ki te 3.

$$\frac{3r}{3}=\frac{-6s+2t-4}{3}$$

Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.

$$r=\frac{-6s+2t-4}{3}$$

Whakawehe -4+2t-6s ki te 3.

$$r=\frac{2t}{3}-2s-\frac{4}{3}$$

Whakaoti mō s

$$s=\frac{t}{3}-\frac{r}{2}-\frac{2}{3}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te r+2s.

$$3r+6s=2t-4$$

Tangohia te 3r mai i ngā taha e rua.

$$6s=2t-4-3r$$

He hanga arowhānui tō te whārite.

$$6s=-3r+2t-4$$

Whakawehea ngā taha e rua ki te 6.

$$\frac{6s}{6}=\frac{-3r+2t-4}{6}$$

Mā te whakawehe ki te 6 ka wetekia te whakareanga ki te 6.

$$s=\frac{-3r+2t-4}{6}$$

Whakawehe 2t-4-3r ki te 6.

$$s=\frac{t}{3}-\frac{r}{2}-\frac{2}{3}$$
