240-x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-x=y-240
Tangohia te 240 mai i ngā taha e rua.
\frac{-x}{-1}=\frac{y-240}{-1}
Whakawehea ngā taha e rua ki te -1.
x=\frac{y-240}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x=240-y
Whakawehe y-240 ki te -1.
