Kua tāruatia ki te papatopenga
x=9+4
Whakaarohia te whārite tuarua. Me tāpiri te 4 ki ngā taha e rua.
x=13
Tāpirihia te 9 ki te 4, ka 13.
13^{2}+y=42
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
169+y=42
Tātaihia te 13 mā te pū o 2, kia riro ko 169.
y=42-169
Tangohia te 169 mai i ngā taha e rua.
y=-127
Tangohia te 169 i te 42, ka -127.
x=13 y=-127
Kua oti te pūnaha te whakatau.
