\left(x+1\right)\times 3+\left(2x-2\right)\times 3=\left(2x+2\right)\times 4
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -1,1 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 2\left(x-1\right)\left(x+1\right), arā, te tauraro pātahi he tino iti rawa te kitea o 2x-2,x+1,x-1.
3x+3+\left(2x-2\right)\times 3=\left(2x+2\right)\times 4
Whakamahia te āhuatanga tohatoha hei whakarea te x+1 ki te 3.
3x+3+6x-6=\left(2x+2\right)\times 4
Whakamahia te āhuatanga tohatoha hei whakarea te 2x-2 ki te 3.
9x+3-6=\left(2x+2\right)\times 4
Pahekotia te 3x me 6x, ka 9x.
9x-3=\left(2x+2\right)\times 4
Tangohia te 6 i te 3, ka -3.
9x-3=8x+8
Whakamahia te āhuatanga tohatoha hei whakarea te 2x+2 ki te 4.
9x-3-8x=8
Tangohia te 8x mai i ngā taha e rua.
x-3=8
Pahekotia te 9x me -8x, ka x.
x=8+3
Me tāpiri te 3 ki ngā taha e rua.
x=11
Tāpirihia te 8 ki te 3, ka 11.
