Kua tāruatia ki te papatopenga
10x=9\left(x+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 10\left(x+1\right), arā, te tauraro pātahi he tino iti rawa te kitea o x+1,10.
10x=9x+9
Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te x+1.
10x-9x=9
Tangohia te 9x mai i ngā taha e rua.
x=9
Pahekotia te 10x me -9x, ka x.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
