300=100+7n-77
Whakamahia te āhuatanga tohatoha hei whakarea te n-11 ki te 7.
300=23+7n
Tangohia te 77 i te 100, ka 23.
23+7n=300
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
7n=300-23
Tangohia te 23 mai i ngā taha e rua.
7n=277
Tangohia te 23 i te 300, ka 277.
n=\frac{277}{7}
Whakawehea ngā taha e rua ki te 7.
