Kua tāruatia ki te papatopenga
-9x+15=3y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-9x=3y-15
Tangohia te 15 mai i ngā taha e rua.
\frac{-9x}{-9}=\frac{3y-15}{-9}
Whakawehea ngā taha e rua ki te -9.
x=\frac{3y-15}{-9}
Mā te whakawehe ki te -9 ka wetekia te whakareanga ki te -9.
x=\frac{5-y}{3}
Whakawehe -15+3y ki te -9.
3y=15-9x
He hanga arowhānui tō te whārite.
\frac{3y}{3}=\frac{15-9x}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{15-9x}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
y=5-3x
Whakawehe -9x+15 ki te 3.
