Kua tāruatia ki te papatopenga
3y+2.2=5.5
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3y=5.5-2.2
Tangohia te 2.2 mai i ngā taha e rua.
3y=3.3
Tangohia te 2.2 i te 5.5, ka 3.3.
y=\frac{3.3}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{33}{30}
Whakarohaina te \frac{3.3}{3} mā te whakarea i te taurunga me te tauraro ki te 10.
y=\frac{11}{10}
Whakahekea te hautanga \frac{33}{30} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
