Kua tāruatia ki te papatopenga
1+\left(x-1\right)\left(-2\right)=0
Tē taea kia ōrite te tāupe x ki 1 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x-1.
1-2x+2=0
Whakamahia te āhuatanga tohatoha hei whakarea te x-1 ki te -2.
3-2x=0
Tāpirihia te 1 ki te 2, ka 3.
-2x=-3
Tangohia te 3 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-3}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{3}{2}
Ka taea te hautanga \frac{-3}{-2} te whakamāmā ki te \frac{3}{2} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
