Whakaoti mō x
x=\frac{y-2z}{15}
Whakaoti mō y
y=15x+2z
Pātaitai
Linear Equation
y=15x+2z
Tohaina
Kua tāruatia ki te papatopenga
15x+2z=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
15x=y-2z
Tangohia te 2z mai i ngā taha e rua.
\frac{15x}{15}=\frac{y-2z}{15}
Whakawehea ngā taha e rua ki te 15.
x=\frac{y-2z}{15}
Mā te whakawehe ki te 15 ka wetekia te whakareanga ki te 15.
