Whakaoti mō x
x=\frac{25-y^{2}}{9}
Whakaoti mō y (complex solution)
y=-\sqrt{25-9x}
y=\sqrt{25-9x}
Whakaoti mō y
y=\sqrt{25-9x}

Tohaina
Kua tāruatia ki te papatopenga
25=9x+y^{2}
Tāpirihia te 7 ki te 18, ka 25.
9x+y^{2}=25
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
9x=25-y^{2}
Tangohia te y^{2} mai i ngā taha e rua.
\frac{9x}{9}=\frac{25-y^{2}}{9}
Whakawehea ngā taha e rua ki te 9.
x=\frac{25-y^{2}}{9}
Mā te whakawehe ki te 9 ka wetekia te whakareanga ki te 9.
