Kua tāruatia ki te papatopenga
\left(x-1\right)\times 3=\left(x+1\right)\times 2
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.
3x-3=\left(x+1\right)\times 2
Whakamahia te āhuatanga tohatoha hei whakarea te x-1 ki te 3.
3x-3=2x+2
Whakamahia te āhuatanga tohatoha hei whakarea te x+1 ki te 2.
3x-3-2x=2
Tangohia te 2x mai i ngā taha e rua.
x-3=2
Pahekotia te 3x me -2x, ka x.
x=2+3
Me tāpiri te 3 ki ngā taha e rua.
x=5
Tāpirihia te 2 ki te 3, ka 5.
