225-72y=1
Tātaihia te 15 mā te pū o 2, kia riro ko 225.
-72y=1-225
Tangohia te 225 mai i ngā taha e rua.
-72y=-224
Tangohia te 225 i te 1, ka -224.
y=\frac{-224}{-72}
Whakawehea ngā taha e rua ki te -72.
y=\frac{28}{9}
Whakahekea te hautanga \frac{-224}{-72} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -8.
