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