Kua tāruatia ki te papatopenga
40-y=x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-y=x-40
Tangohia te 40 mai i ngā taha e rua.
\frac{-y}{-1}=\frac{x-40}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{x-40}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=40-x
Whakawehe x-40 ki te -1.
