Answer 1

a-primul numar
b-al doilea numar
c-al treilea numar
a+b+c=733.597
a+b=627.504=>a=627.504-b=>a=627.504-(495.743-c)=>a=131.761+c
b+c=495.743=>b=495.743-c
Inlocuim
131.761+c+495.743-c+c=733.597
627.504+c=733.597
c=733.597-627.504
c=106.093
____________
a=131.761+c=131.761+106.093
a=237.854
________________

b=495.743-c=495.743-106.093
b=389.650
______________
237.854+389.650+106.093=
627.504+106.093=733.597
