300-10x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-10x=y-300
Tangohia te 300 mai i ngā taha e rua.
\frac{-10x}{-10}=\frac{y-300}{-10}
Whakawehea ngā taha e rua ki te -10.
x=\frac{y-300}{-10}
Mā te whakawehe ki te -10 ka wetekia te whakareanga ki te -10.
x=-\frac{y}{10}+30
Whakawehe y-300 ki te -10.
