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