Answer 1

a+b+c=197423
a+b=113448
b+c=133633
---------------------
a=?;b=?c=?

113448+c=197423
c=197423-113448
c=83975

a+133633=197423
a=197423-133633
a=63790

83975+b+63790=197423
b=197423-147765
b=49658

83975+49658+63790=197423

Answer 2

a+b+c=197.423
a+b= 113.448=> b=113.448-a
onlocuiesc mai sus si voi avea
a+113.448-a+c=197.423
113.448+c=197.423=> c=197.423-113.448=> c=83.975

a+b+c=197.423
b+c=133.633=> c=133.633-b
inlocuim mai sus si vom avea
a+b+133.633-b=197.423
a+133.633=197.423=> a=197.423-133.633=> a=63.970

a+b+c=197.423
63.970+b+83.975=197.423
147.945+b=197.423
b=197.423-147.945
b=49.478

verificam
a+b=?
63.970+49.478=113.448

b+c=?
49.658+83.975=133.633
