Kua tāruatia ki te papatopenga
2\left(3x-7\right)=5\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 6\left(x+1\right), arā, te tauraro pātahi he tino iti rawa te kitea o 3x+3,6.
6x-14=5\left(x+1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 3x-7.
6x-14=5x+5
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+1.
6x-14-5x=5
Tangohia te 5x mai i ngā taha e rua.
x-14=5
Pahekotia te 6x me -5x, ka x.
x=5+14
Me tāpiri te 14 ki ngā taha e rua.
x=19
Tāpirihia te 5 ki te 14, ka 19.
