Kua tāruatia ki te papatopenga
13x+7=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
13x=y-7
Tangohia te 7 mai i ngā taha e rua.
\frac{13x}{13}=\frac{y-7}{13}
Whakawehea ngā taha e rua ki te 13.
x=\frac{y-7}{13}
Mā te whakawehe ki te 13 ka wetekia te whakareanga ki te 13.
