Kua tāruatia ki te papatopenga
13x+45=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
13x=y-45
Tangohia te 45 mai i ngā taha e rua.
\frac{13x}{13}=\frac{y-45}{13}
Whakawehea ngā taha e rua ki te 13.
x=\frac{y-45}{13}
Mā te whakawehe ki te 13 ka wetekia te whakareanga ki te 13.
