2.5+0.15p-0.4p=0
Tangohia te 0.4p mai i ngā taha e rua.
2.5-0.25p=0
Pahekotia te 0.15p me -0.4p, ka -0.25p.
-0.25p=-2.5
Tangohia te 2.5 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
p=\frac{-2.5}{-0.25}
Whakawehea ngā taha e rua ki te -0.25.
p=\frac{-250}{-25}
Whakarohaina te \frac{-2.5}{-0.25} mā te whakarea i te taurunga me te tauraro ki te 100.
p=10
Whakawehea te -250 ki te -25, kia riro ko 10.
