Kua tāruatia ki te papatopenga
3x-9=A
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3x=A+9
Me tāpiri te 9 ki ngā taha e rua.
\frac{3x}{3}=\frac{A+9}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{A+9}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
x=\frac{A}{3}+3
Whakawehe A+9 ki te 3.
