Kua tāruatia ki te papatopenga
x-120500=0.02x
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.
x-120500-0.02x=0
Tangohia te 0.02x mai i ngā taha e rua.
0.98x-120500=0
Pahekotia te x me -0.02x, ka 0.98x.
0.98x=120500
Me tāpiri te 120500 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{120500}{0.98}
Whakawehea ngā taha e rua ki te 0.98.
x=\frac{12050000}{98}
Whakarohaina te \frac{120500}{0.98} mā te whakarea i te taurunga me te tauraro ki te 100.
x=\frac{6025000}{49}
Whakahekea te hautanga \frac{12050000}{98} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
