Kua tāruatia ki te papatopenga
5\left(x+4\right)=4x
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 5x, arā, te tauraro pātahi he tino iti rawa te kitea o x,5.
5x+20=4x
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+4.
5x+20-4x=0
Tangohia te 4x mai i ngā taha e rua.
x+20=0
Pahekotia te 5x me -4x, ka x.
x=-20
Tangohia te 20 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
