Answer 2

$\it a)\ \ \overline{46x}\ \vdots\ 3 \Rightarrow (4+6+x)\ \vdots\ 3 \Rightarrow (10+x)\ \vdots\ 3 \Rightarrow x\in\{2,\ \ 5,\ \ 8\}\\ \\ \\ b)\ \ 3\not|\ \overline{x234} \Rightarrow 3\not|\ (x+2+3+4) \Rightarrow 3\not|\ (9+x) \Rightarrow x\in\{1,\ 2,\ 4,\ 5,\ 7,\ 8\}\\ \\ \\ c)\ \ \overline{x3xx}\ \vdots\ 9 \Rightarrow (x+3+x+x)\ \vdots\ 9 \Rightarrow (3x+3)\ \vdots9 \Rightarrow x\in\{2,\ \ 5,\ \ 8\}$

$\it d)\ 9\not|\ \overline{x315} \Rightarrow 9\not|\ (x+3+1+5) \Rightarrow 9\not|\ (9+x) \Rightarrow x\in\{1,\ 2,\ 3,\ 4,\ 5,\ 6,7,\ 8\}$
