Răspuns :
a+b=6456
a=5b
5b+b=6456
6b=6456=>b= [tex]\frac{6456}{6}[/tex]=1076
a=5b=5·1076=5380
Deci:
a=5380
b=1076
a=5b
5b+b=6456
6b=6456=>b= [tex]\frac{6456}{6}[/tex]=1076
a=5b=5·1076=5380
Deci:
a=5380
b=1076
notam primul nr prin x,atunci al doilea este 5x. alcatuim ecuatia: x+5x=6456; 6x=6456; x=1076-primul numar; 5*1076=5380-al doilea numar.
