DE_{9}+5=D^{2}E
Whakareatia te D ki te D, ka D^{2}.
D^{2}E=DE_{9}+5
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{D^{2}E}{D^{2}}=\frac{DE_{9}+5}{D^{2}}
Whakawehea ngā taha e rua ki te D^{2}.
E=\frac{DE_{9}+5}{D^{2}}
Mā te whakawehe ki te D^{2} ka wetekia te whakareanga ki te D^{2}.
