Kua tāruatia ki te papatopenga
2\left(2x+1\right)=x
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 2x, arā, te tauraro pātahi he tino iti rawa te kitea o x,2.
4x+2=x
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x+1.
4x+2-x=0
Tangohia te x mai i ngā taha e rua.
3x+2=0
Pahekotia te 4x me -x, ka 3x.
3x=-2
Tangohia te 2 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-2}{3}
Whakawehea ngā taha e rua ki te 3.
x=-\frac{2}{3}
Ka taea te hautanga \frac{-2}{3} te tuhi anō ko -\frac{2}{3} mā te tango i te tohu tōraro.
