-2x-3y=8-6
Tangohia te 6 mai i ngā taha e rua.
-2x-3y=2
Tangohia te 6 i te 8, ka 2.
-2x=2+3y
Me tāpiri te 3y ki ngā taha e rua.
-2x=3y+2
He hanga arowhānui tō te whārite.
\frac{-2x}{-2}=\frac{3y+2}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{3y+2}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=-\frac{3y}{2}-1
Whakawehe 2+3y ki te -2.
-2x-3y=8-6
Tangohia te 6 mai i ngā taha e rua.
-2x-3y=2
Tangohia te 6 i te 8, ka 2.
-3y=2+2x
Me tāpiri te 2x ki ngā taha e rua.
-3y=2x+2
He hanga arowhānui tō te whārite.
\frac{-3y}{-3}=\frac{2x+2}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{2x+2}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{-2x-2}{3}
Whakawehe 2+2x ki te -3.
