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
