Tohaina
Kua tāruatia ki te papatopenga
0=m\times 16+4+m\left(-8\right)
Tē taea kia ōrite te tāupe m ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te m.
0=8m+4
Pahekotia te m\times 16 me m\left(-8\right), ka 8m.
8m+4=0
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
8m=-4
Tangohia te 4 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
m=\frac{-4}{8}
Whakawehea ngā taha e rua ki te 8.
m=-\frac{1}{2}
Whakahekea te hautanga \frac{-4}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
