2+125y+275y=10
Me tāpiri te 275y ki ngā taha e rua.
2+400y=10
Pahekotia te 125y me 275y, ka 400y.
400y=10-2
Tangohia te 2 mai i ngā taha e rua.
400y=8
Tangohia te 2 i te 10, ka 8.
y=\frac{8}{400}
Whakawehea ngā taha e rua ki te 400.
y=\frac{1}{50}
Whakahekea te hautanga \frac{8}{400} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.
