Kua tāruatia ki te papatopenga
-\frac{2}{3}x+3=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-\frac{2}{3}x=y-3
Tangohia te 3 mai i ngā taha e rua.
\frac{-\frac{2}{3}x}{-\frac{2}{3}}=\frac{y-3}{-\frac{2}{3}}
Whakawehea ngā taha e rua o te whārite ki te -\frac{2}{3}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{y-3}{-\frac{2}{3}}
Mā te whakawehe ki te -\frac{2}{3} ka wetekia te whakareanga ki te -\frac{2}{3}.
x=\frac{9-3y}{2}
Whakawehe y-3 ki te -\frac{2}{3} mā te whakarea y-3 ki te tau huripoki o -\frac{2}{3}.
