\sqrt{3y+16}+1-1=3-1
Me tango 1 mai i ngā taha e rua o te whārite.
\sqrt{3y+16}=3-1
Mā te tango i te 1 i a ia ake anō ka toe ko te 0.
\sqrt{3y+16}=2
Tango 1 mai i 3.
3y+16=4
Pūruatia ngā taha e rua o te whārite.
3y+16-16=4-16
Me tango 16 mai i ngā taha e rua o te whārite.
3y=4-16
Mā te tango i te 16 i a ia ake anō ka toe ko te 0.
3y=-12
Tango 16 mai i 4.
\frac{3y}{3}=-\frac{12}{3}
Whakawehea ngā taha e rua ki te 3.
y=-\frac{12}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
y=-4
Whakawehe -12 ki te 3.
