Kua tāruatia ki te papatopenga
x=12-4
Whakaarohia te whārite tuarua. Tangohia te 4 mai i ngā taha e rua.
x=8
Tangohia te 4 i te 12, ka 8.
8=4y
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
\frac{8}{4}=y
Whakawehea ngā taha e rua ki te 4.
2=y
Whakawehea te 8 ki te 4, kia riro ko 2.
y=2
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=8 y=2
Kua oti te pūnaha te whakatau.
