Kua tāruatia ki te papatopenga
2a+2b=112
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2a=112-2b
Tangohia te 2b mai i ngā taha e rua.
\frac{2a}{2}=\frac{112-2b}{2}
Whakawehea ngā taha e rua ki te 2.
a=\frac{112-2b}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
a=56-b
Whakawehe 112-2b ki te 2.
2a+2b=112
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2b=112-2a
Tangohia te 2a mai i ngā taha e rua.
\frac{2b}{2}=\frac{112-2a}{2}
Whakawehea ngā taha e rua ki te 2.
b=\frac{112-2a}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
b=56-a
Whakawehe 112-2a ki te 2.
