Kua tāruatia ki te papatopenga
x\times 2=\left(x+1\right)\times 3
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -1,0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te x\left(x+1\right), arā, te tauraro pātahi he tino iti rawa te kitea o x+1,x.
x\times 2=3x+3
Whakamahia te āhuatanga tohatoha hei whakarea te x+1 ki te 3.
x\times 2-3x=3
Tangohia te 3x mai i ngā taha e rua.
-x=3
Pahekotia te x\times 2 me -3x, ka -x.
x=-3
Me whakarea ngā taha e rua ki te -1.
