Whakaoti i te 012aT004(20-a)=20*009

$$012 a T 004 ( 20 - a ) = 20 \times 009$$

Whakaoti mō T_0

Ngā Upane mō te Whakaoti Whārite Rārangi

He hanga arowhānui tō te whārite.

$$\text{true}$$

He pono tēnei mō tētahi T_{0} ahakoa.

Ngā Upane Otinga

Whakareatia te 0 ki te 12, ka 0.

$$0aT_{0}\times 0\times 4\left(20-a\right)=20\times 0\times 0\times 9$$

Whakareatia te 0 ki te 0, ka 0.

$$0aT_{0}\times 4\left(20-a\right)=20\times 0\times 0\times 9$$

Whakareatia te 0 ki te 4, ka 0.

$$0aT_{0}\left(20-a\right)=20\times 0\times 0\times 9$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$0=20\times 0\times 0\times 9$$

Whakareatia te 20 ki te 0, ka 0.

$$0=0\times 0\times 9$$

Whakareatia te 0 ki te 0, ka 0.

$$0=0\times 9$$

Whakareatia te 0 ki te 9, ka 0.

$$0=0$$

Whakatauritea te 0 me te 0.

$$\text{true}$$

He pono tēnei mō tētahi a ahakoa.
