Kua tāruatia ki te papatopenga
x-1=0.5x
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-1-0.5x=0
Tangohia te 0.5x mai i ngā taha e rua.
0.5x-1=0
Pahekotia te x me -0.5x, ka 0.5x.
0.5x=1
Me tāpiri te 1 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{1}{0.5}
Whakawehea ngā taha e rua ki te 0.5.
x=\frac{10}{5}
Whakarohaina te \frac{1}{0.5} mā te whakarea i te taurunga me te tauraro ki te 10.
x=2
Whakawehea te 10 ki te 5, kia riro ko 2.
