a-primul termen
a=1836-703
a=1133
1133+1836+c=3978
c=3978-1133-1836
c=1009
1133+1836+c=3999
c=3999-1133-1836
c=1030
c=[1009;1030]
a=1836-703
a=1133
1133+1836+c=3978
c=3978-1133-1836
c=1009
1133+1836+c=3999
c=3999-1133-1836
c=1030
c=[1009;1030]
a+b+c>3978
a+b+c=3999
a=1836-703 =1133
1133+1836+c>3978
c >3978-1133-1836
c>1009
3999-3978=21 c=cel mult egal cu 1009+21=1030
c estee cuprins intre 1010 si 1030 deoarece c>1009
