5x+2880=4x
Me whakarea ngā taha e rua o te whārite ki te 60, arā, te tauraro pātahi he tino iti rawa te kitea o 12,15.
5x+2880-4x=0
Tangohia te 4x mai i ngā taha e rua.
x+2880=0
Pahekotia te 5x me -4x, ka x.
x=-2880
Tangohia te 2880 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
