Kua tāruatia ki te papatopenga
5x=7y-2
Tangohia te 4 i te 2, ka -2.
\frac{5x}{5}=\frac{7y-2}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{7y-2}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
5x=7y-2
Tangohia te 4 i te 2, ka -2.
7y-2=5x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
7y=5x+2
Me tāpiri te 2 ki ngā taha e rua.
\frac{7y}{7}=\frac{5x+2}{7}
Whakawehea ngā taha e rua ki te 7.
y=\frac{5x+2}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
