300-60x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-60x=y-300
Tangohia te 300 mai i ngā taha e rua.
\frac{-60x}{-60}=\frac{y-300}{-60}
Whakawehea ngā taha e rua ki te -60.
x=\frac{y-300}{-60}
Mā te whakawehe ki te -60 ka wetekia te whakareanga ki te -60.
x=-\frac{y}{60}+5
Whakawehe y-300 ki te -60.
