Ko te tau i whakarea ki te kore ka hua ko te kore.
0+168x=81
Pahekotia te x me 167x, ka 168x.
168x=81
Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{81}{168}
Whakawehea ngā taha e rua ki te 168.
x=\frac{27}{56}
Whakahekea te hautanga \frac{81}{168} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
