Kua tāruatia ki te papatopenga
5x+15=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
5x=y-15
Tangohia te 15 mai i ngā taha e rua.
\frac{5x}{5}=\frac{y-15}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{y-15}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
x=\frac{y}{5}-3
Whakawehe y-15 ki te 5.
