Kua tāruatia ki te papatopenga
4x-6x=5y
Tangohia te 6x mai i ngā taha e rua.
-2x=5y
Pahekotia te 4x me -6x, ka -2x.
\frac{-2x}{-2}=\frac{5y}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{5y}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=-\frac{5y}{2}
Whakawehe 5y ki te -2.
5y+6x=4x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
5y=4x-6x
Tangohia te 6x mai i ngā taha e rua.
5y=-2x
Pahekotia te 4x me -6x, ka -2x.
\frac{5y}{5}=-\frac{2x}{5}
Whakawehea ngā taha e rua ki te 5.
y=-\frac{2x}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
