Kua tāruatia ki te papatopenga
5x+5y=d
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
5x=d-5y
Tangohia te 5y mai i ngā taha e rua.
\frac{5x}{5}=\frac{d-5y}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{d-5y}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
x=\frac{d}{5}-y
Whakawehe d-5y ki te 5.
