Whakaoti mō y
y=\frac{x-9z}{5}
Whakaoti mō x
x=5y+9z
Tohaina
Kua tāruatia ki te papatopenga
5y+9z=x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
5y=x-9z
Tangohia te 9z mai i ngā taha e rua.
\frac{5y}{5}=\frac{x-9z}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{x-9z}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
