Graph
Tohaina
Kua tāruatia ki te papatopenga
y=2x
Whakawehea te 4x ki te 2, kia riro ko 2x.
2x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{2x}{2}=\frac{y}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{y}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=2x
Whakawehea te 4x ki te 2, kia riro ko 2x.
