Tohaina
Kua tāruatia ki te papatopenga
-8x=2y-10
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{-8x}{-8}=\frac{2y-10}{-8}
Whakawehea ngā taha e rua ki te -8.
x=\frac{2y-10}{-8}
Mā te whakawehe ki te -8 ka wetekia te whakareanga ki te -8.
x=\frac{5-y}{4}
Whakawehe -10+2y ki te -8.
2y=-8x+10
Me tāpiri te 10 ki ngā taha e rua.
2y=10-8x
He hanga arowhānui tō te whārite.
\frac{2y}{2}=\frac{10-8x}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{10-8x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=5-4x
Whakawehe -8x+10 ki te 2.
