Tohaina
Kua tāruatia ki te papatopenga
5a-4\left(a-11\right)=80
Me whakarea ngā taha e rua o te whārite ki te 20, arā, te tauraro pātahi he tino iti rawa te kitea o 4,5.
5a-4a+44=80
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te a-11.
a+44=80
Pahekotia te 5a me -4a, ka a.
a=80-44
Tangohia te 44 mai i ngā taha e rua.
a=36
Tangohia te 44 i te 80, ka 36.
