Kua tāruatia ki te papatopenga
500=100+8n-8
Whakamahia te āhuatanga tohatoha hei whakarea te n-1 ki te 8.
500=92+8n
Tangohia te 8 i te 100, ka 92.
92+8n=500
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
8n=500-92
Tangohia te 92 mai i ngā taha e rua.
8n=408
Tangohia te 92 i te 500, ka 408.
n=\frac{408}{8}
Whakawehea ngā taha e rua ki te 8.
n=51
Whakawehea te 408 ki te 8, kia riro ko 51.
