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