4a+2b+6=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
4a+6=y-2b
Tangohia te 2b mai i ngā taha e rua.
4a=y-2b-6
Tangohia te 6 mai i ngā taha e rua.
\frac{4a}{4}=\frac{y-2b-6}{4}
Whakawehea ngā taha e rua ki te 4.
a=\frac{y-2b-6}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
a=\frac{y}{4}-\frac{b}{2}-\frac{3}{2}
Whakawehe y-2b-6 ki te 4.
4a+2b+6=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2b+6=y-4a
Tangohia te 4a mai i ngā taha e rua.
2b=y-4a-6
Tangohia te 6 mai i ngā taha e rua.
\frac{2b}{2}=\frac{y-4a-6}{2}
Whakawehea ngā taha e rua ki te 2.
b=\frac{y-4a-6}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
b=\frac{y}{2}-2a-3
Whakawehe y-4a-6 ki te 2.
