50=100+2n-2
Whakamahia te āhuatanga tohatoha hei whakarea te n-1 ki te 2.
50=98+2n
Tangohia te 2 i te 100, ka 98.
98+2n=50
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2n=50-98
Tangohia te 98 mai i ngā taha e rua.
2n=-48
Tangohia te 98 i te 50, ka -48.
n=\frac{-48}{2}
Whakawehea ngā taha e rua ki te 2.
n=-24
Whakawehea te -48 ki te 2, kia riro ko -24.
