( frac{3}{x}+frac{4}{y}=1 quad x y=frac{12}{x}+frac{16}{y}=4 ) ( frac{4}{x}+frac{2}{y}=frac{11}{12} times 3-frac{12}{x}+frac{6}{y}=frac{33}{12} ) ( frac{10}{y}=4-frac{3311}{1, x} ) ( Rightarrow frac{18}{y}=frac{3}{4} ) ( y=124 ) ( frac{3}{x}+frac{4}{8}=1 ) ( =frac{3}{x}=1 / 2 ) ( x=6 ) thenee ( x=6, y=8 )
