-10x=8y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{-10x}{-10}=\frac{8y}{-10}
Whakawehea ngā taha e rua ki te -10.
x=\frac{8y}{-10}
Mā te whakawehe ki te -10 ka wetekia te whakareanga ki te -10.
x=-\frac{4y}{5}
Whakawehe 8y ki te -10.
8y=-10x
He hanga arowhānui tō te whārite.
\frac{8y}{8}=-\frac{10x}{8}
Whakawehea ngā taha e rua ki te 8.
y=-\frac{10x}{8}
Mā te whakawehe ki te 8 ka wetekia te whakareanga ki te 8.
y=-\frac{5x}{4}
Whakawehe -10x ki te 8.
