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