Kua tāruatia ki te papatopenga
\left(x+1\right)\times 4=x\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,x+1.
4x+4=x\times 3
Whakamahia te āhuatanga tohatoha hei whakarea te x+1 ki te 4.
4x+4-x\times 3=0
Tangohia te x\times 3 mai i ngā taha e rua.
x+4=0
Pahekotia te 4x me -x\times 3, ka x.
x=-4
Tangohia te 4 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
