Kua tāruatia ki te papatopenga
-x+5=25
Pūruatia ngā taha e rua o te whārite.
-x+5-5=25-5
Me tango 5 mai i ngā taha e rua o te whārite.
-x=25-5
Mā te tango i te 5 i a ia ake anō ka toe ko te 0.
-x=20
Tango 5 mai i 25.
\frac{-x}{-1}=\frac{20}{-1}
Whakawehea ngā taha e rua ki te -1.
x=\frac{20}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x=-20
Whakawehe 20 ki te -1.
