2x+y+2x=5y
Me tāpiri te 2x ki ngā taha e rua.
4x+y=5y
Pahekotia te 2x me 2x, ka 4x.
4x=5y-y
Tangohia te y mai i ngā taha e rua.
4x=4y
Pahekotia te 5y me -y, ka 4y.
x=y
Me whakakore te 4 ki ngā taha e rua.
2x+y-5y=-2x
Tangohia te 5y mai i ngā taha e rua.
2x-4y=-2x
Pahekotia te y me -5y, ka -4y.
-4y=-2x-2x
Tangohia te 2x mai i ngā taha e rua.
-4y=-4x
Pahekotia te -2x me -2x, ka -4x.
y=x
Me whakakore te -4 ki ngā taha e rua.
