Answer 1

[tex] \frac{a+b}{2} =192 =\ \textgreater \ a+b=192*2=\ \textgreater \ a+b=384\\ a:b=5r6=\ \textgreater \ a=5b+6 \\ 5b+6+b=384=\ \textgreater \ 6b=384-6=\ \textgreater \ b=378:6=\ \textgreater \ b=63 \\ a=5*63+6=\ \textgreater \ a=321[/tex]

Answer 2

(a+b):2=192 a+b=384 a:b=5 rest 6 => (prin regula inpartirii cu rest) a=5b+6 a+b=384 5b+6+b=384 |-6 6b=378 |:6 b=63 a=5•63+6 a=321
