Kua tāruatia ki te papatopenga
6-7x=0
Tē taea kia ōrite te tāupe x ki -\frac{1}{2} nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te 2x+1.
-7x=-6
Tangohia te 6 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-6}{-7}
Whakawehea ngā taha e rua ki te -7.
x=\frac{6}{7}
Ka taea te hautanga \frac{-6}{-7} te whakamāmā ki te \frac{6}{7} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
