Tāpirihia te 28000 ki te 18500, ka 46500.
46500+1500x=64120
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
1500x=64120-46500
Tangohia te 46500 mai i ngā taha e rua.
1500x=17620
Tangohia te 46500 i te 64120, ka 17620.
x=\frac{17620}{1500}
Whakawehea ngā taha e rua ki te 1500.
x=\frac{881}{75}
Whakahekea te hautanga \frac{17620}{1500} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 20.
