Kua tāruatia ki te papatopenga
2\left(4x+7\right)=3\left(2x+9\right)
Tē taea kia ōrite te tāupe x ki -\frac{9}{2} nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 2\left(2x+9\right), arā, te tauraro pātahi he tino iti rawa te kitea o 2x+9,2.
8x+14=3\left(2x+9\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 4x+7.
8x+14=6x+27
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x+9.
8x+14-6x=27
Tangohia te 6x mai i ngā taha e rua.
2x+14=27
Pahekotia te 8x me -6x, ka 2x.
2x=27-14
Tangohia te 14 mai i ngā taha e rua.
2x=13
Tangohia te 14 i te 27, ka 13.
x=\frac{13}{2}
Whakawehea ngā taha e rua ki te 2.
