18-16x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-16x=y-18
Tangohia te 18 mai i ngā taha e rua.
\frac{-16x}{-16}=\frac{y-18}{-16}
Whakawehea ngā taha e rua ki te -16.
x=\frac{y-18}{-16}
Mā te whakawehe ki te -16 ka wetekia te whakareanga ki te -16.
x=-\frac{y}{16}+\frac{9}{8}
Whakawehe y-18 ki te -16.
