Kua tāruatia ki te papatopenga
7x=-10y
He hanga arowhānui tō te whārite.
\frac{7x}{7}=-\frac{10y}{7}
Whakawehea ngā taha e rua ki te 7.
x=-\frac{10y}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
-10y=7x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{-10y}{-10}=\frac{7x}{-10}
Whakawehea ngā taha e rua ki te -10.
y=\frac{7x}{-10}
Mā te whakawehe ki te -10 ka wetekia te whakareanga ki te -10.
y=-\frac{7x}{10}
Whakawehe 7x ki te -10.
