Kua tāruatia ki te papatopenga
25\times 200=5500+25x\left(-1\right)
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 25x, arā, te tauraro pātahi he tino iti rawa te kitea o x,25x.
5000=5500+25x\left(-1\right)
Whakareatia te 25 ki te 200, ka 5000.
5000=5500-25x
Whakareatia te 25 ki te -1, ka -25.
5500-25x=5000
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-25x=5000-5500
Tangohia te 5500 mai i ngā taha e rua.
-25x=-500
Tangohia te 5500 i te 5000, ka -500.
x=\frac{-500}{-25}
Whakawehea ngā taha e rua ki te -25.
x=20
Whakawehea te -500 ki te -25, kia riro ko 20.
