(a+b)-136 =545
246:2x2=246
a+246=591
a=591-246
a=543
(543+b)-136=545
543+b=545+136
543+b=681
b=681-543
b=138
(543+138)-136=545

A+b-136=545
dublul jumatatii numarului 246 este tot 246,adica 246:2=123;123*2=246
atunci
a+246=591
a=591-246
a=245
245+b-136=545
245-136=109
109+b=545
b=545-109
b=436

a+b-136=545
245+435-136=545
