Kua tāruatia ki te papatopenga
8x=2y+9
He hanga arowhānui tō te whārite.
\frac{8x}{8}=\frac{2y+9}{8}
Whakawehea ngā taha e rua ki te 8.
x=\frac{2y+9}{8}
Mā te whakawehe ki te 8 ka wetekia te whakareanga ki te 8.
x=\frac{y}{4}+\frac{9}{8}
Whakawehe 2y+9 ki te 8.
2y+9=8x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2y=8x-9
Tangohia te 9 mai i ngā taha e rua.
\frac{2y}{2}=\frac{8x-9}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{8x-9}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=4x-\frac{9}{2}
Whakawehe 8x-9 ki te 2.
