Kua tāruatia ki te papatopenga
-\frac{7}{3}x+4=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-\frac{7}{3}x=y-4
Tangohia te 4 mai i ngā taha e rua.
\frac{-\frac{7}{3}x}{-\frac{7}{3}}=\frac{y-4}{-\frac{7}{3}}
Whakawehea ngā taha e rua o te whārite ki te -\frac{7}{3}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{y-4}{-\frac{7}{3}}
Mā te whakawehe ki te -\frac{7}{3} ka wetekia te whakareanga ki te -\frac{7}{3}.
x=\frac{12-3y}{7}
Whakawehe y-4 ki te -\frac{7}{3} mā te whakarea y-4 ki te tau huripoki o -\frac{7}{3}.
