Kua tāruatia ki te papatopenga
5\left(2x+1\right)=8\left(x+5\right)
Tē taea kia ōrite te tāupe x ki -5 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 5\left(x+5\right), arā, te tauraro pātahi he tino iti rawa te kitea o x+5,5.
10x+5=8\left(x+5\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 2x+1.
10x+5=8x+40
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te x+5.
10x+5-8x=40
Tangohia te 8x mai i ngā taha e rua.
2x+5=40
Pahekotia te 10x me -8x, ka 2x.
2x=40-5
Tangohia te 5 mai i ngā taha e rua.
2x=35
Tangohia te 5 i te 40, ka 35.
x=\frac{35}{2}
Whakawehea ngā taha e rua ki te 2.
