Kua tāruatia ki te papatopenga
2x=x\times 4-\left(x-3\right)\times 5
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 2x\left(x-3\right), arā, te tauraro pātahi he tino iti rawa te kitea o x-3,2x-6,2x.
2x=x\times 4-\left(5x-15\right)
Whakamahia te āhuatanga tohatoha hei whakarea te x-3 ki te 5.
2x=x\times 4-5x+15
Hei kimi i te tauaro o 5x-15, kimihia te tauaro o ia taurangi.
2x=-x+15
Pahekotia te x\times 4 me -5x, ka -x.
2x+x=15
Me tāpiri te x ki ngā taha e rua.
3x=15
Pahekotia te 2x me x, ka 3x.
x=\frac{15}{3}
Whakawehea ngā taha e rua ki te 3.
x=5
Whakawehea te 15 ki te 3, kia riro ko 5.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
