Kua tāruatia ki te papatopenga
1+3x\times 2=12x
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 3x.
1+6x=12x
Whakareatia te 3 ki te 2, ka 6.
1+6x-12x=0
Tangohia te 12x mai i ngā taha e rua.
1-6x=0
Pahekotia te 6x me -12x, ka -6x.
-6x=-1
Tangohia te 1 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-1}{-6}
Whakawehea ngā taha e rua ki te -6.
x=\frac{1}{6}
Ka taea te hautanga \frac{-1}{-6} te whakamāmā ki te \frac{1}{6} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
