\sqrt{6x+1}+9-9=16-9
Me tango 9 mai i ngā taha e rua o te whārite.
\sqrt{6x+1}=16-9
Mā te tango i te 9 i a ia ake anō ka toe ko te 0.
\sqrt{6x+1}=7
Tango 9 mai i 16.
6x+1=49
Pūruatia ngā taha e rua o te whārite.
6x+1-1=49-1
Me tango 1 mai i ngā taha e rua o te whārite.
6x=49-1
Mā te tango i te 1 i a ia ake anō ka toe ko te 0.
6x=48
Tango 1 mai i 49.
\frac{6x}{6}=\frac{48}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{48}{6}
Mā te whakawehe ki te 6 ka wetekia te whakareanga ki te 6.
x=8
Whakawehe 48 ki te 6.
