Tohaina
Kua tāruatia ki te papatopenga
18T+5=a
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
18T=a-5
Tangohia te 5 mai i ngā taha e rua.
\frac{18T}{18}=\frac{a-5}{18}
Whakawehea ngā taha e rua ki te 18.
T=\frac{a-5}{18}
Mā te whakawehe ki te 18 ka wetekia te whakareanga ki te 18.
