Whakaoti i te (x-500)*075+500*01=(1-015)x

$$( x - 500 ) \times 075 + 500 \times 01 = ( 1 - 015 ) x$$

Whakaoti mō x

$$x=0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 0 ki te 75, ka 0.

$$\left(x-500\right)\times 0+500\times 0\times 1=\left(1-0\times 15\right)x$$

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

$$0+500\times 0\times 1=\left(1-0\times 15\right)x$$

Whakareatia te 500 ki te 0, ka 0.

$$0+0\times 1=\left(1-0\times 15\right)x$$

Whakareatia te 0 ki te 1, ka 0.

$$0+0=\left(1-0\times 15\right)x$$

Tāpirihia te 0 ki te 0, ka 0.

$$0=\left(1-0\times 15\right)x$$

Whakareatia te 0 ki te 15, ka 0.

$$0=\left(1-0\right)x$$

Tangohia te 0 i te 1, ka 1.

$$0=1x$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$1x=0$$

Whakaraupapatia anō ngā kīanga tau.

$$x=0$$
