Tohaina
Kua tāruatia ki te papatopenga
P=8500X+\frac{2}{5}
Whakahekea te hautanga \frac{40}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.
8500X+\frac{2}{5}=P
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
8500X=P-\frac{2}{5}
Tangohia te \frac{2}{5} mai i ngā taha e rua.
\frac{8500X}{8500}=\frac{P-\frac{2}{5}}{8500}
Whakawehea ngā taha e rua ki te 8500.
X=\frac{P-\frac{2}{5}}{8500}
Mā te whakawehe ki te 8500 ka wetekia te whakareanga ki te 8500.
X=\frac{P}{8500}-\frac{1}{21250}
Whakawehe P-\frac{2}{5} ki te 8500.
P=8500X+\frac{2}{5}
Whakahekea te hautanga \frac{40}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.
