Kua tāruatia ki te papatopenga
10x+2=y^{2}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
10x=y^{2}-2
Tangohia te 2 mai i ngā taha e rua.
\frac{10x}{10}=\frac{y^{2}-2}{10}
Whakawehea ngā taha e rua ki te 10.
x=\frac{y^{2}-2}{10}
Mā te whakawehe ki te 10 ka wetekia te whakareanga ki te 10.
x=\frac{y^{2}}{10}-\frac{1}{5}
Whakawehe y^{2}-2 ki te 10.
