Kua tāruatia ki te papatopenga
6v-20-8v=0
Tangohia te 8v mai i ngā taha e rua.
-2v-20=0
Pahekotia te 6v me -8v, ka -2v.
-2v=20
Me tāpiri te 20 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
v=\frac{20}{-2}
Whakawehea ngā taha e rua ki te -2.
v=-10
Whakawehea te 20 ki te -2, kia riro ko -10.
