Kua tāruatia ki te papatopenga
16x=120x\times \frac{1}{8}+120
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 120x, arā, te tauraro pātahi he tino iti rawa te kitea o 15,8,x.
16x=\frac{120}{8}x+120
Whakareatia te 120 ki te \frac{1}{8}, ka \frac{120}{8}.
16x=15x+120
Whakawehea te 120 ki te 8, kia riro ko 15.
16x-15x=120
Tangohia te 15x mai i ngā taha e rua.
x=120
Pahekotia te 16x me -15x, ka x.
