Tohaina
Kua tāruatia ki te papatopenga
\sqrt{5x}+2-2=8-2
Me tango 2 mai i ngā taha e rua o te whārite.
\sqrt{5x}=8-2
Mā te tango i te 2 i a ia ake anō ka toe ko te 0.
\sqrt{5x}=6
Tango 2 mai i 8.
5x=36
Pūruatia ngā taha e rua o te whārite.
\frac{5x}{5}=\frac{36}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{36}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
