\sqrt{7x+51}+14-14=18-14
Me tango 14 mai i ngā taha e rua o te whārite.
\sqrt{7x+51}=18-14
Mā te tango i te 14 i a ia ake anō ka toe ko te 0.
\sqrt{7x+51}=4
Tango 14 mai i 18.
7x+51=16
Pūruatia ngā taha e rua o te whārite.
7x+51-51=16-51
Me tango 51 mai i ngā taha e rua o te whārite.
7x=16-51
Mā te tango i te 51 i a ia ake anō ka toe ko te 0.
7x=-35
Tango 51 mai i 16.
\frac{7x}{7}=-\frac{35}{7}
Whakawehea ngā taha e rua ki te 7.
x=-\frac{35}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
x=-5
Whakawehe -35 ki te 7.
