Kua tāruatia ki te papatopenga
10x+15=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
10x=y-15
Tangohia te 15 mai i ngā taha e rua.
\frac{10x}{10}=\frac{y-15}{10}
Whakawehea ngā taha e rua ki te 10.
x=\frac{y-15}{10}
Mā te whakawehe ki te 10 ka wetekia te whakareanga ki te 10.
x=\frac{y}{10}-\frac{3}{2}
Whakawehe y-15 ki te 10.
