Kua tāruatia ki te papatopenga
y=\frac{3}{4}-\frac{1}{4}x
Whakawehea ia wā o 3-x ki te 4, kia riro ko \frac{3}{4}-\frac{1}{4}x.
\frac{3}{4}-\frac{1}{4}x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-\frac{1}{4}x=y-\frac{3}{4}
Tangohia te \frac{3}{4} mai i ngā taha e rua.
\frac{-\frac{1}{4}x}{-\frac{1}{4}}=\frac{y-\frac{3}{4}}{-\frac{1}{4}}
Me whakarea ngā taha e rua ki te -4.
x=\frac{y-\frac{3}{4}}{-\frac{1}{4}}
Mā te whakawehe ki te -\frac{1}{4} ka wetekia te whakareanga ki te -\frac{1}{4}.
x=3-4y
Whakawehe y-\frac{3}{4} ki te -\frac{1}{4} mā te whakarea y-\frac{3}{4} ki te tau huripoki o -\frac{1}{4}.
y=\frac{3}{4}-\frac{1}{4}x
Whakawehea ia wā o 3-x ki te 4, kia riro ko \frac{3}{4}-\frac{1}{4}x.
