0=5v+5
Pahekotia te 6v me -v, ka 5v.
5v+5=0
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
5v=-5
Tangohia te 5 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
v=\frac{-5}{5}
Whakawehea ngā taha e rua ki te 5.
v=-1
Whakawehea te -5 ki te 5, kia riro ko -1.
