a+b+c =396
a = 3b
c = 156
3b+b+156=396
4b=396-156
4b = 240 |:4
b = 60
a =3×60 = 180
proba: 180+60+156=396
a = 3b
c = 156
3b+b+156=396
4b=396-156

a =3×60 = 180
proba: 180+60+156=396
a+b+c=396
a=3×b
c=156
Acum inlocuim numerele in sumasi obtinem:
3×b+b+156=396
4×b+156=396
4×b=396-156
4×b=240
b=240:4
b=60
a=3×b
a=3×60
a=180
Deci a=180
b=60
c=156
Sper ca te-am ajutat! Bafta!!!
