Whakaoti mō x
x=\frac{10y+z}{2}
Whakaoti mō y
y=\frac{x}{5}-\frac{z}{10}
Tohaina
Kua tāruatia ki te papatopenga
2x-10y=z
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2x=z+10y
Me tāpiri te 10y ki ngā taha e rua.
2x=10y+z
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{10y+z}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{10y+z}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=\frac{z}{2}+5y
Whakawehe z+10y ki te 2.
2x-10y=z
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-10y=z-2x
Tangohia te 2x mai i ngā taha e rua.
\frac{-10y}{-10}=\frac{z-2x}{-10}
Whakawehea ngā taha e rua ki te -10.
y=\frac{z-2x}{-10}
Mā te whakawehe ki te -10 ka wetekia te whakareanga ki te -10.
y=\frac{x}{5}-\frac{z}{10}
Whakawehe z-2x ki te -10.
