Kua tāruatia ki te papatopenga
2x+3=28
Pūruatia ngā taha e rua o te whārite.
2x+3-3=28-3
Me tango 3 mai i ngā taha e rua o te whārite.
2x=28-3
Mā te tango i te 3 i a ia ake anō ka toe ko te 0.
2x=25
Tango 3 mai i 28.
\frac{2x}{2}=\frac{25}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{25}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
