a-b=72
a:b=4 rest 3 rezulta a=4b+3
inlocuim in a-b=72
4b+3-b=72
3b=72-3
3b=69
b=69:3
b=23
a-23=72
a=72+23
a=95
a:b=4 rest 3 rezulta a=4b+3
inlocuim in a-b=72
4b+3-b=72
3b=72-3
3b=69
b=69:3
b=23
a-23=72
a=72+23
a=95
a-b=72
a:b=4 rest3 adica a=4b+3
inlocuind a in prima ecuatie obtinem 4b+3-b=72
3b=72-3
3b=69
b=23
a=4*23+3
a=95
a:b=4 rest3 adica a=4b+3
inlocuind a in prima ecuatie obtinem 4b+3-b=72
3b=72-3
3b=69
b=23
a=4*23+3
a=95
