Notăm numerele cu a,b,c.
a = b/2
c = 3a
a+b+c =738
-------------------
a,b,c?
-------
b/2 +b + 3a = 738
b/2 +b +3b/2 = 738
b+2b+3b = 2*738
6b = 2*738
3b = 738
b = 246
a = b/2
a = 123
c= 3a
c = 369
a = b/2
c = 3a
a+b+c =738

a=b/2=>(rezulta)b=2a=6c
c=a/3=>a=3c
a+b+c=738
inlocuim pr a si pe b
6c+3c+c=728
10c=728
c=72.8
b=6*72.8=436.8
a=3*c=218.4 Raspuns:a=218.4
b=436.8
c=72.8
c=a/3=>a=3c

inlocuim pr a si pe b
6c+3c+c=728
