Kua tāruatia ki te papatopenga
6x=9y+12
He hanga arowhānui tō te whārite.
\frac{6x}{6}=\frac{9y+12}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{9y+12}{6}
Mā te whakawehe ki te 6 ka wetekia te whakareanga ki te 6.
x=\frac{3y}{2}+2
Whakawehe 12+9y ki te 6.
12+9y=6x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
9y=6x-12
Tangohia te 12 mai i ngā taha e rua.
\frac{9y}{9}=\frac{6x-12}{9}
Whakawehea ngā taha e rua ki te 9.
y=\frac{6x-12}{9}
Mā te whakawehe ki te 9 ka wetekia te whakareanga ki te 9.
y=\frac{2x-4}{3}
Whakawehe -12+6x ki te 9.
