Tohaina
Kua tāruatia ki te papatopenga
P=2+2W
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 1+W.
2+2W=P
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2W=P-2
Tangohia te 2 mai i ngā taha e rua.
\frac{2W}{2}=\frac{P-2}{2}
Whakawehea ngā taha e rua ki te 2.
W=\frac{P-2}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
W=\frac{P}{2}-1
Whakawehe P-2 ki te 2.
P=2+2W
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 1+W.
