Whakaoti mō a
a=\frac{b}{2}
Whakaoti mō b
b=2a
Tohaina
Kua tāruatia ki te papatopenga
2a=b
Pahekotia te a me a, ka 2a.
\frac{2a}{2}=\frac{b}{2}
Whakawehea ngā taha e rua ki te 2.
a=\frac{b}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
2a=b
Pahekotia te a me a, ka 2a.
b=2a
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
