Kua tāruatia ki te papatopenga
7\times 27=9x
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 7x, arā, te tauraro pātahi he tino iti rawa te kitea o x,7.
189=9x
Whakareatia te 7 ki te 27, ka 189.
9x=189
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{189}{9}
Whakawehea ngā taha e rua ki te 9.
x=21
Whakawehea te 189 ki te 9, kia riro ko 21.
