Kua tāruatia ki te papatopenga
1-9x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-9x=y-1
Tangohia te 1 mai i ngā taha e rua.
\frac{-9x}{-9}=\frac{y-1}{-9}
Whakawehea ngā taha e rua ki te -9.
x=\frac{y-1}{-9}
Mā te whakawehe ki te -9 ka wetekia te whakareanga ki te -9.
x=\frac{1-y}{9}
Whakawehe y-1 ki te -9.
