Question

a+b+c=817.978
503.217:a=17
b:c=13 rest 9

Answer 1

A+b+c=817.978
503.217:a=17
b:c=13 rest 9

a=503.217:17=29.601
a=29.601

b+c=817.978-29.601=788.377

b+c=788.377
b:c=13rest9 (formula impartirii cu rest)
b=(13c+9)

(13c+9)   +c = 788.377
14c=788.377-9=788.368
c=788368:14=56.312
c=56.312

a+c=29.601+56.312=85.913
b=817.978-85.913=732.065
b=732.065
