Tohaina
Kua tāruatia ki te papatopenga
20-2k\times 3=0
Whakareatia te 4 ki te 5, ka 20.
20-6k=0
Whakareatia te 2 ki te 3, ka 6.
-6k=-20
Tangohia te 20 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
k=\frac{-20}{-6}
Whakawehea ngā taha e rua ki te -6.
k=\frac{10}{3}
Whakahekea te hautanga \frac{-20}{-6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.
