Kua tāruatia ki te papatopenga
4=2h+2
Ko te tauaro o -2 ko 2.
2h+2=4
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2h=4-2
Tangohia te 2 mai i ngā taha e rua.
2h=2
Tangohia te 2 i te 4, ka 2.
h=\frac{2}{2}
Whakawehea ngā taha e rua ki te 2.
h=1
Whakawehea te 2 ki te 2, kia riro ko 1.
