Whakaoti i te 2a3b/4=20

$$\frac { 2 a 3 b } { 4 } = 20$$

Whakaoti mō a_3

$$a_{3}=\frac{40}{b}$$

$$b\neq 0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua ki te 4.

$$2a_{3}b=20\times 4$$

Whakareatia te 20 ki te 4, ka 80.

$$2a_{3}b=80$$

He hanga arowhānui tō te whārite.

$$2ba_{3}=80$$

Whakawehea ngā taha e rua ki te 2b.

$$\frac{2ba_{3}}{2b}=\frac{80}{2b}$$

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

$$a_{3}=\frac{80}{2b}$$

Whakawehe 80 ki te 2b.

$$a_{3}=\frac{40}{b}$$

Whakaoti mō b

$$b=\frac{40}{a_{3}}$$

$$a_{3}\neq 0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua ki te 4.

$$2a_{3}b=20\times 4$$

Whakareatia te 20 ki te 4, ka 80.

$$2a_{3}b=80$$

Whakawehea ngā taha e rua ki te 2a_{3}.

$$\frac{2a_{3}b}{2a_{3}}=\frac{80}{2a_{3}}$$

Mā te whakawehe ki te 2a_{3} ka wetekia te whakareanga ki te 2a_{3}.

$$b=\frac{80}{2a_{3}}$$

Whakawehe 80 ki te 2a_{3}.

$$b=\frac{40}{a_{3}}$$
