Kua tāruatia ki te papatopenga
2\left(2x+1\right)=x+1
Tē taea kia ōrite te tāupe x ki -1 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 2\left(x+1\right), arā, te tauraro pātahi he tino iti rawa te kitea o x+1,2.
4x+2=x+1
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x+1.
4x+2-x=1
Tangohia te x mai i ngā taha e rua.
3x+2=1
Pahekotia te 4x me -x, ka 3x.
3x=1-2
Tangohia te 2 mai i ngā taha e rua.
3x=-1
Tangohia te 2 i te 1, ka -1.
x=\frac{-1}{3}
Whakawehea ngā taha e rua ki te 3.
x=-\frac{1}{3}
Ka taea te hautanga \frac{-1}{3} te tuhi anō ko -\frac{1}{3} mā te tango i te tohu tōraro.
