A+b+c=778
a+b=580
b+c=451

580+c=778
c=778-580
c=198

a+451=778
a=778-451
a=327

327+b=580
b=580-327
b=253
2014-10-07T14:31:17+03:00
A+b+c=778
a+b=580
deci 580+c=778
c=778-580
c=198(al 3 nr)

b+c=451
a+541=778
a=778-451
a=327(primul nr)

acum ii adunam pe cei doi ca sa-l aflam pe al 2-lea:198+327=525
525+b=778
b=778-525
b=253 (al 2 nr.)

327+253+198=778

sau direct:778-580=198( 1 nr.) :778-451=327(al.2 nr) 580-327=253(al 3 nr)
