Whakaoti i te r2-A=10

$$r 2 - A = 10$$

Whakaoti mō A

$$A=r_{2}-10$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te r_{2} mai i ngā taha e rua.

$$-A=10-r_{2}$$

Whakawehea ngā taha e rua ki te -1.

$$\frac{-A}{-1}=\frac{10-r_{2}}{-1}$$

Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.

$$A=\frac{10-r_{2}}{-1}$$

Whakawehe 10-r_{2} ki te -1.

$$A=r_{2}-10$$

Whakaoti mō r_2

$$r_{2}=A+10$$

Ngā Upane Otinga

Me tāpiri te A ki ngā taha e rua.

$$r_{2}=10+A$$
