Kua tāruatia ki te papatopenga
3\times 2-5\times 5=60x
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 15x, arā, te tauraro pātahi he tino iti rawa te kitea o 5x,3x.
6-25=60x
Mahia ngā whakarea.
-19=60x
Tangohia te 25 i te 6, ka -19.
60x=-19
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{-19}{60}
Whakawehea ngā taha e rua ki te 60.
x=-\frac{19}{60}
Ka taea te hautanga \frac{-19}{60} te tuhi anō ko -\frac{19}{60} mā te tango i te tohu tōraro.
