Kua tāruatia ki te papatopenga
3x=15-5y
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{15-5y}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{15-5y}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
x=-\frac{5y}{3}+5
Whakawehe 15-5y ki te 3.
15-5y=3x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-5y=3x-15
Tangohia te 15 mai i ngā taha e rua.
\frac{-5y}{-5}=\frac{3x-15}{-5}
Whakawehea ngā taha e rua ki te -5.
y=\frac{3x-15}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
y=-\frac{3x}{5}+3
Whakawehe -15+3x ki te -5.
