Kua tāruatia ki te papatopenga
x=\frac{2}{2}
Whakaarohia te whārite tuarua. Whakawehea ngā taha e rua ki te 2.
x=1
Whakawehea te 2 ki te 2, kia riro ko 1.
2\times 1=4-y
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
2=4-y
Whakareatia te 2 ki te 1, ka 2.
4-y=2
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-y=2-4
Tangohia te 4 mai i ngā taha e rua.
-y=-2
Tangohia te 4 i te 2, ka -2.
y=\frac{-2}{-1}
Whakawehea ngā taha e rua ki te -1.
y=2
Ka taea te hautanga \frac{-2}{-1} te whakamāmā ki te 2 mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
x=1 y=2
Kua oti te pūnaha te whakatau.
