0x\times 8=420+x
Whakareatia te 14 ki te 0, ka 0.
0x=420+x
Whakareatia te 0 ki te 8, ka 0.
0=420+x
Ko te tau i whakarea ki te kore ka hua ko te kore.
420+x=0
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=-420
Tangohia te 420 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
