Răspuns :
Daca a+b=53 atunci inlocuim
53+c=96
c=43
Daca b+c=74 inlocuim
a+74=96
a=22
a+b+c=96
22+b+43=96
b+65=96
b=31
53+c=96
c=43
Daca b+c=74 inlocuim
a+74=96
a=22
a+b+c=96
22+b+43=96
b+65=96
b=31
a=53-b
c=74-b
53-b+b+74-b=96
127-b=96
b=127-96
b=31
a=53-31=22
c=74-31=43
c=74-b
53-b+b+74-b=96
127-b=96
b=127-96
b=31
a=53-31=22
c=74-31=43
