Kua tāruatia ki te papatopenga
455x-900=8100
Tātaihia te 90 mā te pū o 2, kia riro ko 8100.
455x=8100+900
Me tāpiri te 900 ki ngā taha e rua.
455x=9000
Tāpirihia te 8100 ki te 900, ka 9000.
x=\frac{9000}{455}
Whakawehea ngā taha e rua ki te 455.
x=\frac{1800}{91}
Whakahekea te hautanga \frac{9000}{455} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
