Tohaina
Kua tāruatia ki te papatopenga
3x+9=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3x=y-9
Tangohia te 9 mai i ngā taha e rua.
\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 y-9 ki te 3.
