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