Answer 1

$a+b+c=66 \\ \\ a+b=43 \\ \\ b+c=34 \\ \\ \\ 43+c=66 \\ c=66-43 \\ \\ \boxed{c=23} \\ \\ a+34=66 \\ a=66-34 \\ \\ \boxed{a=32} \\ \\ 32+b=43 \\ b=43-32 \\ \\ \boxed{b=11} \\ \\ \boxed{A:32,11,23}$

Answer 2

c=66-43; c=23; a=66-34; a=32; b=66-23-32; b=11; răspunsul corect este a) 32,11, 23
