Answer 2

Answer:

x= y = 1/4

Step-by-step explanation:

$\frac{1}{x} + \frac{1}{y} = 8(given) \\ \frac{4}{x} - \frac{2}{y} = 8(given) \\ on \: equaing \: above \: and \: below \: equation \\ \frac{1}{x} + \frac{1}{y} = \frac{4}{x} - \frac{2}{y} \\ \frac{3}{y} = \\ x = y \\ so \\ \frac{1}{x} + \frac{1}{x} = 8 \\ \frac{2}{x} = 8 \\ x = \frac{1}{4} \\ since \: x = y = \frac{1}{4}$
