Kua tāruatia ki te papatopenga
3x=y+9
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{y+9}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{y+9}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
x=\frac{y}{3}+3
Whakawehe 9+y ki te 3.
9+y=3x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
y=3x-9
Tangohia te 9 mai i ngā taha e rua.
