Question

Asta e intrebarea din poza

Answer 1

$\overline{abc} + \overline{bc} + c = 292$

$a = 1$

$b = 9$

$c =4$

$194 + 94 + 4 = 292$

$\overline{abc} + \overline{ab} + a = 581$

$a = 5$

$b = 2$

$c = 4$

$524 + 52 + 5 = 581$

Answer 2

$a) \: \: \overline{abc} + \overline{bc} + \overline{c} = 292 \\ 1a + 2b + 3c = 292 \\ u(3c) = 2 \\ \implies \: c = 4 \\ \\ u(2b) = 8 \\ \implies \: b _{1} = 4 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: b _{2} = 9 \\ \implies \: a _{1} = 1 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: a _{2} = 2\\ \\ 194 + 94 + 4 = 292 \: \: \: \: \sqrt{} \\ 244 + 44 + 4 = 292 \: \: \: \: \sqrt{}$

Nu ma lasa sa raspund si la a doua :( ma da afara mere nus dc
