Kua tāruatia ki te papatopenga
4000-125\times 4000=1250x
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 125x, arā, te tauraro pātahi he tino iti rawa te kitea o 125x,x.
4000-500000=1250x
Whakareatia te -125 ki te 4000, ka -500000.
-496000=1250x
Tangohia te 500000 i te 4000, ka -496000.
1250x=-496000
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{-496000}{1250}
Whakawehea ngā taha e rua ki te 1250.
x=-\frac{1984}{5}
Whakahekea te hautanga \frac{-496000}{1250} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 250.
