Kua tāruatia ki te papatopenga
y=4x-25x_{2}
Tātaihia te 5 mā te pū o 2, kia riro ko 25.
4x-25x_{2}=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
4x=y+25x_{2}
Me tāpiri te 25x_{2} ki ngā taha e rua.
4x=25x_{2}+y
He hanga arowhānui tō te whārite.
\frac{4x}{4}=\frac{25x_{2}+y}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{25x_{2}+y}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=4x-25x_{2}
Tātaihia te 5 mā te pū o 2, kia riro ko 25.
4x-25x_{2}=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-25x_{2}=y-4x
Tangohia te 4x mai i ngā taha e rua.
\frac{-25x_{2}}{-25}=\frac{y-4x}{-25}
Whakawehea ngā taha e rua ki te -25.
x_{2}=\frac{y-4x}{-25}
Mā te whakawehe ki te -25 ka wetekia te whakareanga ki te -25.
x_{2}=\frac{4x-y}{25}
Whakawehe y-4x ki te -25.
