Answer 2

Answer:

$take \: 1st \: equation \\ \frac{2}{x} = 4 \\ \\ 2 = 4x \\ \\ x = \frac{2}{4} \\ \\ x = \frac{1}{4} \\ \\ now \: take \: 2nd \: equation \\ \frac{2}{y} = 8 \ \\ 2 = 8y \\ \\ y = \frac{2}{8} \\ \\ y = \frac{1}{4} \\ \\ now \: value \: of \: x = \frac{1}{2} \: and \: y = \frac{1}{4} \\ put \: in \: the \: given \: equation \\ \\ x - y = \frac{1}{2} - \frac{1}{4} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: = \frac{2 - 1}{4} \\ \\ \: \: \: \: \: \: \: \: \: \: \: = \frac{1}{4}$
