Whakaoti mō n
n=\frac{t_{n}+15}{40}
Whakaoti mō t_n
t_{n}=40n-15
Tohaina
Kua tāruatia ki te papatopenga
40n-15=t_{n}
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
40n=t_{n}+15
Me tāpiri te 15 ki ngā taha e rua.
\frac{40n}{40}=\frac{t_{n}+15}{40}
Whakawehea ngā taha e rua ki te 40.
n=\frac{t_{n}+15}{40}
Mā te whakawehe ki te 40 ka wetekia te whakareanga ki te 40.
n=\frac{t_{n}}{40}+\frac{3}{8}
Whakawehe t_{n}+15 ki te 40.
