Whakaoti i te 5r-2t=10

$$5 r - 2 t = 10$$

Whakaoti mō r

$$r=\frac{2\left(t+5\right)}{5}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me tāpiri te 2t ki ngā taha e rua.

$$5r=10+2t$$

He hanga arowhānui tō te whārite.

$$5r=2t+10$$

Whakawehea ngā taha e rua ki te 5.

$$\frac{5r}{5}=\frac{2t+10}{5}$$

Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.

$$r=\frac{2t+10}{5}$$

Whakawehe 10+2t ki te 5.

$$r=\frac{2t}{5}+2$$

Whakaoti mō t

$$t=\frac{5\left(r-2\right)}{2}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 5r mai i ngā taha e rua.

$$-2t=10-5r$$

Whakawehea ngā taha e rua ki te -2.

$$\frac{-2t}{-2}=\frac{10-5r}{-2}$$

Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.

$$t=\frac{10-5r}{-2}$$

Whakawehe 10-5r ki te -2.

$$t=\frac{5r}{2}-5$$
