Kua tāruatia ki te papatopenga
-x+5=4y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-x=4y-5
Tangohia te 5 mai i ngā taha e rua.
\frac{-x}{-1}=\frac{4y-5}{-1}
Whakawehea ngā taha e rua ki te -1.
x=\frac{4y-5}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x=5-4y
Whakawehe 4y-5 ki te -1.
4y=5-x
He hanga arowhānui tō te whārite.
\frac{4y}{4}=\frac{5-x}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{5-x}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
