Kua tāruatia ki te papatopenga
-\frac{1}{4}x-4=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-\frac{1}{4}x=y+4
Me tāpiri te 4 ki ngā taha e rua.
\frac{-\frac{1}{4}x}{-\frac{1}{4}}=\frac{y+4}{-\frac{1}{4}}
Me whakarea ngā taha e rua ki te -4.
x=\frac{y+4}{-\frac{1}{4}}
Mā te whakawehe ki te -\frac{1}{4} ka wetekia te whakareanga ki te -\frac{1}{4}.
x=-4y-16
Whakawehe y+4 ki te -\frac{1}{4} mā te whakarea y+4 ki te tau huripoki o -\frac{1}{4}.
