Kua tāruatia ki te papatopenga
-2x-3=-y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-2x=-y+3
Me tāpiri te 3 ki ngā taha e rua.
-2x=3-y
He hanga arowhānui tō te whārite.
\frac{-2x}{-2}=\frac{3-y}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{3-y}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{y-3}{2}
Whakawehe -y+3 ki te -2.
-y=-2x-3
He hanga arowhānui tō te whārite.
\frac{-y}{-1}=\frac{-2x-3}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{-2x-3}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=2x+3
Whakawehe -2x-3 ki te -1.
