Kua tāruatia ki te papatopenga
4=\left(x-3\right)\times 8+x
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara 0,3 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te x\left(x-3\right), arā, te tauraro pātahi he tino iti rawa te kitea o x^{2}-3x,x,x-3.
4=8x-24+x
Whakamahia te āhuatanga tohatoha hei whakarea te x-3 ki te 8.
4=9x-24
Pahekotia te 8x me x, ka 9x.
9x-24=4
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
9x=4+24
Me tāpiri te 24 ki ngā taha e rua.
9x=28
Tāpirihia te 4 ki te 24, ka 28.
x=\frac{28}{9}
Whakawehea ngā taha e rua ki te 9.
