Kua tāruatia ki te papatopenga
-4x+5=3y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-4x=3y-5
Tangohia te 5 mai i ngā taha e rua.
\frac{-4x}{-4}=\frac{3y-5}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{3y-5}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
x=\frac{5-3y}{4}
Whakawehe 3y-5 ki te -4.
3y=5-4x
He hanga arowhānui tō te whārite.
\frac{3y}{3}=\frac{5-4x}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{5-4x}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
