Kua tāruatia ki te papatopenga
80x-45=60
Pahekotia te 20x me 60x, ka 80x.
80x=60+45
Me tāpiri te 45 ki ngā taha e rua.
80x=105
Tāpirihia te 60 ki te 45, ka 105.
x=\frac{105}{80}
Whakawehea ngā taha e rua ki te 80.
x=\frac{21}{16}
Whakahekea te hautanga \frac{105}{80} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
