20k+10=12k
Whakaarohia te whārite tuatahi. Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 4k+2.
20k+10-12k=0
Tangohia te 12k mai i ngā taha e rua.
8k+10=0
Pahekotia te 20k me -12k, ka 8k.
8k=-10
Tangohia te 10 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
k=\frac{-10}{8}
Whakawehea ngā taha e rua ki te 8.
k=-\frac{5}{4}
Whakahekea te hautanga \frac{-10}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

Kua oti te pūnaha te whakatau.
