21x+16y=385
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
21x=385-16y
Tangohia te 16y mai i ngā taha e rua.
\frac{21x}{21}=\frac{385-16y}{21}
Whakawehea ngā taha e rua ki te 21.
x=\frac{385-16y}{21}
Mā te whakawehe ki te 21 ka wetekia te whakareanga ki te 21.
x=-\frac{16y}{21}+\frac{55}{3}
Whakawehe 385-16y ki te 21.
21x+16y=385
