Kua tāruatia ki te papatopenga
15x+3=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
15x=y-3
Tangohia te 3 mai i ngā taha e rua.
\frac{15x}{15}=\frac{y-3}{15}
Whakawehea ngā taha e rua ki te 15.
x=\frac{y-3}{15}
Mā te whakawehe ki te 15 ka wetekia te whakareanga ki te 15.
x=\frac{y}{15}-\frac{1}{5}
Whakawehe y-3 ki te 15.
