Kua tāruatia ki te papatopenga
-9x-5=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-9x=y+5
Me tāpiri te 5 ki ngā taha e rua.
\frac{-9x}{-9}=\frac{y+5}{-9}
Whakawehea ngā taha e rua ki te -9.
x=\frac{y+5}{-9}
Mā te whakawehe ki te -9 ka wetekia te whakareanga ki te -9.
x=\frac{-y-5}{9}
Whakawehe y+5 ki te -9.
