Kua tāruatia ki te papatopenga
2x=3n-55
Tangohia te 70 i te 15, ka -55.
3n-55=2x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3n=2x+55
Me tāpiri te 55 ki ngā taha e rua.
\frac{3n}{3}=\frac{2x+55}{3}
Whakawehea ngā taha e rua ki te 3.
n=\frac{2x+55}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
2x=3n-55
Tangohia te 70 i te 15, ka -55.
\frac{2x}{2}=\frac{3n-55}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{3n-55}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
