Kua tāruatia ki te papatopenga
\sqrt{4y+16}-1=1
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\sqrt{4y+16}=1+1
Me tāpiri te 1 ki ngā taha e rua.
\sqrt{4y+16}=2
Tāpirihia te 1 ki te 1, ka 2.
4y+16=4
Pūruatia ngā taha e rua o te whārite.
4y+16-16=4-16
Me tango 16 mai i ngā taha e rua o te whārite.
4y=4-16
Mā te tango i te 16 i a ia ake anō ka toe ko te 0.
4y=-12
Tango 16 mai i 4.
\frac{4y}{4}=-\frac{12}{4}
Whakawehea ngā taha e rua ki te 4.
y=-\frac{12}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=-3
Whakawehe -12 ki te 4.
