Kua tāruatia ki te papatopenga
2x=y+1.6
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{y+1.6}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{y+1.6}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=\frac{y}{2}+\frac{4}{5}
Whakawehe y+1.6 ki te 2.
y+1.6=2x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
y=2x-1.6
Tangohia te 1.6 mai i ngā taha e rua.
