Kua tāruatia ki te papatopenga
55\times 10\times 5=10-y
Whakareatia ngā taha e rua o te whārite ki te 5.
550\times 5=10-y
Whakareatia te 55 ki te 10, ka 550.
2750=10-y
Whakareatia te 550 ki te 5, ka 2750.
10-y=2750
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-y=2750-10
Tangohia te 10 mai i ngā taha e rua.
-y=2740
Tangohia te 10 i te 2750, ka 2740.
y=-2740
Me whakarea ngā taha e rua ki te -1.
