150-20x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-20x=y-150
Tangohia te 150 mai i ngā taha e rua.
\frac{-20x}{-20}=\frac{y-150}{-20}
Whakawehea ngā taha e rua ki te -20.
x=\frac{y-150}{-20}
Mā te whakawehe ki te -20 ka wetekia te whakareanga ki te -20.
x=-\frac{y}{20}+\frac{15}{2}
Whakawehe y-150 ki te -20.
