Kua tāruatia ki te papatopenga
-80n+360=0
Pahekotia te 2n me -82n, ka -80n.
-80n=-360
Tangohia te 360 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
n=\frac{-360}{-80}
Whakawehea ngā taha e rua ki te -80.
n=\frac{9}{2}
Whakahekea te hautanga \frac{-360}{-80} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -40.
