Kua tāruatia ki te papatopenga
50x=y-120
Tangohia te 120 mai i ngā taha e rua.
\frac{50x}{50}=\frac{y-120}{50}
Whakawehea ngā taha e rua ki te 50.
x=\frac{y-120}{50}
Mā te whakawehe ki te 50 ka wetekia te whakareanga ki te 50.
x=\frac{y}{50}-\frac{12}{5}
Whakawehe y-120 ki te 50.
y=50x+120
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
