Kua tāruatia ki te papatopenga
5\sqrt{x}+4-4=12-4
Me tango 4 mai i ngā taha e rua o te whārite.
5\sqrt{x}=12-4
Mā te tango i te 4 i a ia ake anō ka toe ko te 0.
5\sqrt{x}=8
Tango 4 mai i 12.
\frac{5\sqrt{x}}{5}=\frac{8}{5}
Whakawehea ngā taha e rua ki te 5.
\sqrt{x}=\frac{8}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
x=\frac{64}{25}
Pūruatia ngā taha e rua o te whārite.
