[tex]a+b+c=962[/tex]
[tex]b=3*a[/tex]
[tex]c=3*b => c=3*(3*a) => c=9*a[/tex]
Asadar:
[tex]a+3a+9a=962 <=> 13*a=962 => a= \frac{962}{13} => a=74[/tex]
[tex] \left \{ {{b=3*a} \atop {a=74}} \right. => b=3*74 => b=222[/tex]
[tex] \left \{ {{c=3*b} \atop {b=222}} \right. => c=3*222 => c=666[/tex]
Verificare:
[tex]74+222+666=296+666=962[/tex]
