-2x-2y=10-1
Tangohia te 1 mai i ngā taha e rua.
-2x-2y=9
Tangohia te 1 i te 10, ka 9.
-2x=9+2y
Me tāpiri te 2y ki ngā taha e rua.
-2x=2y+9
He hanga arowhānui tō te whārite.
\frac{-2x}{-2}=\frac{2y+9}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{2y+9}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=-y-\frac{9}{2}
Whakawehe 9+2y ki te -2.
-2x-2y=10-1
Tangohia te 1 mai i ngā taha e rua.
-2x-2y=9

-2y=9+2x
Me tāpiri te 2x ki ngā taha e rua.
-2y=2x+9
He hanga arowhānui tō te whārite.
\frac{-2y}{-2}=\frac{2x+9}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{2x+9}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=-x-\frac{9}{2}
Whakawehe 9+2x ki te -2.
