Tohaina
Kua tāruatia ki te papatopenga
4\times 4a+36=3\times 5a
Me whakarea ngā taha e rua o te whārite ki te 36, arā, te tauraro pātahi he tino iti rawa te kitea o 9,12.
16a+36=3\times 5a
Whakareatia te 4 ki te 4, ka 16.
16a+36=15a
Whakareatia te 3 ki te 5, ka 15.
16a+36-15a=0
Tangohia te 15a mai i ngā taha e rua.
a+36=0
Pahekotia te 16a me -15a, ka a.
a=-36
Tangohia te 36 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
