Kua tāruatia ki te papatopenga
\left(x-1\right)\times 2=x+3
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -3,1 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te \left(x-1\right)\left(x+3\right), arā, te tauraro pātahi he tino iti rawa te kitea o x+3,x-1.
2x-2=x+3
Whakamahia te āhuatanga tohatoha hei whakarea te x-1 ki te 2.
2x-2-x=3
Tangohia te x mai i ngā taha e rua.
x-2=3
Pahekotia te 2x me -x, ka x.
x=3+2
Me tāpiri te 2 ki ngā taha e rua.
x=5
Tāpirihia te 3 ki te 2, ka 5.
