Whakareatia te 180 ki te 13, ka 2340. Whakareatia te 120 ki te 0, ka 0.

$$2340x+0\times 86x-300x=16740$$

Whakareatia te 0 ki te 86, ka 0.

$$2340x+0x-300x=16740$$

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

$$2340x+0-300x=16740$$

Pahekotia te 2340x me -300x, ka 2040x.

$$2040x+0=16740$$

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

$$2040x=16740$$

Whakawehea ngā taha e rua ki te 2040.

$$x=\frac{16740}{2040}$$

Whakahekea te hautanga \frac{16740}{2040} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 60.
