Kua tāruatia ki te papatopenga
\sqrt{2x+4}+2-2=8-2
Me tango 2 mai i ngā taha e rua o te whārite.
\sqrt{2x+4}=8-2
Mā te tango i te 2 i a ia ake anō ka toe ko te 0.
\sqrt{2x+4}=6
Tango 2 mai i 8.
2x+4=36
Pūruatia ngā taha e rua o te whārite.
2x+4-4=36-4
Me tango 4 mai i ngā taha e rua o te whārite.
2x=36-4
Mā te tango i te 4 i a ia ake anō ka toe ko te 0.
2x=32
Tango 4 mai i 36.
\frac{2x}{2}=\frac{32}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{32}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=16
Whakawehe 32 ki te 2.
