Answer 1

$3)\frac{x}{y}=\frac{2}{3} \ \ \ =\ \textgreater \ \frac{x}{2}=\frac{y}{3}=k \\\\ x=2k \\ y=3k \\\\\\ \frac{3x+y}{x-y}=\frac{3*2k+3k}{2k-3k}= \frac{6k+3k}{-k}= \frac{9k}{-k} \to \boxed{-9} \\\\\\\ 4) \\8m...........12zile \\ 24m...........x \\\\ x=\frac{8* \not12}{\not24} \\\\ x=\frac{8}{2} \\\\ \boxed{x=4 \ zile}$
