Kua tāruatia ki te papatopenga
3\times 3x+48=8x
Me whakarea ngā taha e rua o te whārite ki te 24, arā, te tauraro pātahi he tino iti rawa te kitea o 8,3.
9x+48=8x
Whakareatia te 3 ki te 3, ka 9.
9x+48-8x=0
Tangohia te 8x mai i ngā taha e rua.
x+48=0
Pahekotia te 9x me -8x, ka x.
x=-48
Tangohia te 48 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
