Kua tāruatia ki te papatopenga
\left(x+1\right)\times 4+\left(x-1\right)\times 2=35
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -1,1 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te \left(x-1\right)\left(x+1\right), arā, te tauraro pātahi he tino iti rawa te kitea o x-1,x+1,x^{2}-1.
4x+4+\left(x-1\right)\times 2=35
Whakamahia te āhuatanga tohatoha hei whakarea te x+1 ki te 4.
4x+4+2x-2=35
Whakamahia te āhuatanga tohatoha hei whakarea te x-1 ki te 2.
6x+4-2=35
Pahekotia te 4x me 2x, ka 6x.
6x+2=35
Tangohia te 2 i te 4, ka 2.
6x=35-2
Tangohia te 2 mai i ngā taha e rua.
6x=33
Tangohia te 2 i te 35, ka 33.
x=\frac{33}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{11}{2}
Whakahekea te hautanga \frac{33}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
