Kua tāruatia ki te papatopenga
5x=90-9y
He hanga arowhānui tō te whārite.
\frac{5x}{5}=\frac{90-9y}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{90-9y}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
x=-\frac{9y}{5}+18
Whakawehe 90-9y ki te 5.
90-9y=5x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-9y=5x-90
Tangohia te 90 mai i ngā taha e rua.
\frac{-9y}{-9}=\frac{5x-90}{-9}
Whakawehea ngā taha e rua ki te -9.
y=\frac{5x-90}{-9}
Mā te whakawehe ki te -9 ka wetekia te whakareanga ki te -9.
y=-\frac{5x}{9}+10
Whakawehe -90+5x ki te -9.
