Tohaina
Kua tāruatia ki te papatopenga
2x+2=16
Pūruatia ngā taha e rua o te whārite.
2x+2-2=16-2
Me tango 2 mai i ngā taha e rua o te whārite.
2x=16-2
Mā te tango i te 2 i a ia ake anō ka toe ko te 0.
2x=14
Tango 2 mai i 16.
\frac{2x}{2}=\frac{14}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{14}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=7
Whakawehe 14 ki te 2.
