Kua tāruatia ki te papatopenga
-3x=-3+y-6
Tangohia te 6 mai i ngā taha e rua.
-3x=-9+y
Tangohia te 6 i te -3, ka -9.
-3x=y-9
He hanga arowhānui tō te whārite.
\frac{-3x}{-3}=\frac{y-9}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{y-9}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
x=-\frac{y}{3}+3
Whakawehe -9+y ki te -3.
-3+y=6-3x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
y=6-3x+3
Me tāpiri te 3 ki ngā taha e rua.
y=9-3x
Tāpirihia te 6 ki te 3, ka 9.
