Whakaoti mō y
y=7-x^{2}
Whakaoti mō x (complex solution)
x=-\sqrt{7-y}
x=\sqrt{7-y}
Whakaoti mō x

Kua tāruatia ki te papatopenga
7-y=x^{2}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-y=x^{2}-7
Tangohia te 7 mai i ngā taha e rua.
\frac{-y}{-1}=\frac{x^{2}-7}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{x^{2}-7}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=7-x^{2}
Whakawehe x^{2}-7 ki te -1.
