Kua tāruatia ki te papatopenga
4x-16=2y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
4x=2y+16
Me tāpiri te 16 ki ngā taha e rua.
\frac{4x}{4}=\frac{2y+16}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{2y+16}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=\frac{y}{2}+4
Whakawehe 16+2y ki te 4.
2y=4x-16
He hanga arowhānui tō te whārite.
\frac{2y}{2}=\frac{4x-16}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{4x-16}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=2x-8
Whakawehe -16+4x ki te 2.
