Kua tāruatia ki te papatopenga
y=64-12
Whakaarohia te whārite tuarua. Tangohia te 12 mai i ngā taha e rua.
y=52
Tangohia te 12 i te 64, ka 52.
x+52=48
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
x=48-52
Tangohia te 52 mai i ngā taha e rua.
x=-4
Tangohia te 52 i te 48, ka -4.
x=-4 y=52
Kua oti te pūnaha te whakatau.
