Kua tāruatia ki te papatopenga
8n-15-3n=0
Tangohia te 3n mai i ngā taha e rua.
5n-15=0
Pahekotia te 8n me -3n, ka 5n.
5n=15
Me tāpiri te 15 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
n=\frac{15}{5}
Whakawehea ngā taha e rua ki te 5.
n=3
Whakawehea te 15 ki te 5, kia riro ko 3.
