2x-y=19-5
Tangohia te 5 mai i ngā taha e rua.
2x-y=14
Tangohia te 5 i te 19, ka 14.
2x=14+y
Me tāpiri te y ki ngā taha e rua.
2x=y+14
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{y+14}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{y+14}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=\frac{y}{2}+7
Whakawehe 14+y ki te 2.
5-y=19-2x
Tangohia te 2x mai i ngā taha e rua.
-y=19-2x-5
Tangohia te 5 mai i ngā taha e rua.
-y=14-2x
Tangohia te 5 i te 19, ka 14.
\frac{-y}{-1}=\frac{14-2x}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{14-2x}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=2x-14
Whakawehe 14-2x ki te -1.
