Kua tāruatia ki te papatopenga
2x-10=2x\times 6
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 8x, arā, te tauraro pātahi he tino iti rawa te kitea o 8x,4.
2x-10=12x
Whakareatia te 2 ki te 6, ka 12.
2x-10-12x=0
Tangohia te 12x mai i ngā taha e rua.
-10x-10=0
Pahekotia te 2x me -12x, ka -10x.
-10x=10
Me tāpiri te 10 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{10}{-10}
Whakawehea ngā taha e rua ki te -10.
x=-1
Whakawehea te 10 ki te -10, kia riro ko -1.
