Kua tāruatia ki te papatopenga
\frac{5}{24}n+45=85
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{5}{24}n=85-45
Tangohia te 45 mai i ngā taha e rua.
\frac{5}{24}n=40
Tangohia te 45 i te 85, ka 40.
n=40\times \frac{24}{5}
Me whakarea ngā taha e rua ki te \frac{24}{5}, te tau utu o \frac{5}{24}.
n=\frac{40\times 24}{5}
Tuhia te 40\times \frac{24}{5} hei hautanga kotahi.
n=\frac{960}{5}
Whakareatia te 40 ki te 24, ka 960.
n=192
Whakawehea te 960 ki te 5, kia riro ko 192.
