Whakaoti mō n
n = \frac{72}{5} = 14\frac{2}{5} = 14.4
Tohaina
Kua tāruatia ki te papatopenga
8\left(n-9\right)=3n
Me whakarea ngā taha e rua o te whārite ki te 24, arā, te tauraro pātahi he tino iti rawa te kitea o 3,8.
8n-72=3n
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te n-9.
8n-72-3n=0
Tangohia te 3n mai i ngā taha e rua.
5n-72=0
Pahekotia te 8n me -3n, ka 5n.
5n=72
Me tāpiri te 72 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
n=\frac{72}{5}
Whakawehea ngā taha e rua ki te 5.
