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