Kua tāruatia ki te papatopenga
3A+2A+A+5000=77000
Pahekotia te A me 2A, ka 3A.
5A+A+5000=77000
Pahekotia te 3A me 2A, ka 5A.
6A+5000=77000
Pahekotia te 5A me A, ka 6A.
6A=77000-5000
Tangohia te 5000 mai i ngā taha e rua.
6A=72000
Tangohia te 5000 i te 77000, ka 72000.
A=\frac{72000}{6}
Whakawehea ngā taha e rua ki te 6.
A=12000
Whakawehea te 72000 ki te 6, kia riro ko 12000.
