Whakaarohia te whārite tuatahi. Whakareatia te 0 ki te 5, ka 0.

$$258=0A\times 10^{2}+A\times 10$$

Tātaihia te 10 mā te pū o 2, kia riro ko 100.

$$258=0A\times 100+A\times 10$$

Whakareatia te 0 ki te 100, ka 0.

$$258=0A+A\times 10$$

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

$$258=0+A\times 10$$

Ko te tau i tāpiria he kore ka hua koia tonu.

$$258=A\times 10$$

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

$$A\times 10=258$$

Whakawehea ngā taha e rua ki te 10.

$$A=\frac{258}{10}$$

Whakahekea te hautanga \frac{258}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$A=\frac{129}{5}$$

Whakaarohia te whārite tuarua. Tātaihia te 6 mā te pū o 2, kia riro ko 36.

$$a=6-2\times 36$$

Whakareatia te 2 ki te 36, ka 72.

$$a=6-72$$

Tangohia te 72 i te 6, ka -66.

$$a=-66$$

Whakaarohia te whārite tuatoru. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$b=-66$$

Whakaarohia te whārite tuawhā. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$c=-66$$

Kua oti te pūnaha te whakatau.

$$A=\frac{129}{5} a=-66 b=-66 c=-66$$
