Kua tāruatia ki te papatopenga
y=0x^{2}-x+7
Whakareatia te 0 ki te 4, ka 0.
y=0-x+7
Ko te tau i whakarea ki te kore ka hua ko te kore.
y=7-x
Tāpirihia te 0 ki te 7, ka 7.
7-x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-x=y-7
Tangohia te 7 mai i ngā taha e rua.
\frac{-x}{-1}=\frac{y-7}{-1}
Whakawehea ngā taha e rua ki te -1.
x=\frac{y-7}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x=7-y
Whakawehe y-7 ki te -1.
y=0x^{2}-x+7
Whakareatia te 0 ki te 4, ka 0.
y=0-x+7
Ko te tau i whakarea ki te kore ka hua ko te kore.
y=7-x
Tāpirihia te 0 ki te 7, ka 7.
