-\frac{1}{4}x+3=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-\frac{1}{4}x=y-3
Tangohia te 3 mai i ngā taha e rua.
\frac{-\frac{1}{4}x}{-\frac{1}{4}}=\frac{y-3}{-\frac{1}{4}}
Me whakarea ngā taha e rua ki te -4.
x=\frac{y-3}{-\frac{1}{4}}
Mā te whakawehe ki te -\frac{1}{4} ka wetekia te whakareanga ki te -\frac{1}{4}.
x=12-4y
Whakawehe y-3 ki te -\frac{1}{4} mā te whakarea y-3 ki te tau huripoki o -\frac{1}{4}.
