Tohaina
Kua tāruatia ki te papatopenga
3x+2=A
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3x=A-2
Tangohia te 2 mai i ngā taha e rua.
\frac{3x}{3}=\frac{A-2}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{A-2}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
