Kua tāruatia ki te papatopenga
2x=2-y
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{2-y}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{2-y}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=-\frac{y}{2}+1
Whakawehe 2-y ki te 2.
2-y=2x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-y=2x-2
Tangohia te 2 mai i ngā taha e rua.
\frac{-y}{-1}=\frac{2x-2}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{2x-2}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=2-2x
Whakawehe -2+2x ki te -1.
