Kua tāruatia ki te papatopenga
x\times 3+x+2=3
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -2,0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te x\left(x+2\right), arā, te tauraro pātahi he tino iti rawa te kitea o x+2,x,x^{2}+2x.
4x+2=3
Pahekotia te x\times 3 me x, ka 4x.
4x=3-2
Tangohia te 2 mai i ngā taha e rua.
4x=1
Tangohia te 2 i te 3, ka 1.
x=\frac{1}{4}
Whakawehea ngā taha e rua ki te 4.
