Kua tāruatia ki te papatopenga
1500=100+x\left(-10\right)
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.
100+x\left(-10\right)=1500
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x\left(-10\right)=1500-100
Tangohia te 100 mai i ngā taha e rua.
x\left(-10\right)=1400
Tangohia te 100 i te 1500, ka 1400.
x=\frac{1400}{-10}
Whakawehea ngā taha e rua ki te -10.
x=-140
Whakawehea te 1400 ki te -10, kia riro ko -140.
