========================

 \frac{1}{2x}  - \ \frac{1}{y}  \:  =  \:  - 1   =  > u  - 2v   =   - 2 \\  \\  \\  \frac{1}{x}   +  \frac{1}{2y}  \:  =  \: 8 =  >  2u \:  +  v \:  =  \: 16 \\  \\ multiplying \: 2 \: in  \: eq \: 2 \: and \: v \: in \: eq1 \\  \\ u \:  -  \: 2v \:  =  \:  - 2 \\ 4u \:  -  \: 2v \:  =  \: 32   \\  -  -  -  -  -  -  -  -  -  -  \\ 5u \:  -  \: 0 \:  =  \: 30 \\  \\ u \:  =  \:  \frac{30}{5}  =  \: 6   \:  -  \: eq \: 3 \\  \\ substiuting \: eq \: in \: 3 \: in \: eq \: 1 \\  \\ u \:  -  \: 2v \:  =  \:  - 2 \\  \\ 6 \:  -  \: 2v \:  =  \:  - 2 \\  \\ 2v \:  =  \: 6 \:  -  \: 2 \:  =  \: 4 \\  \\ v \:  =  \:  \frac{4}{2}  =  \: 2 \\  \\ v \:  =  \:  \frac{1}{y}  =  \: 2\:  =  \:  \frac{1}{2}  \\  \\ u \:  =  \:  \frac{1}{x}  =  \: 6 \:  =  \:  \frac{1}{6}  \\  \\ so \\  \\  \: x \:  =  \:  \frac{1}{2}  \\  \\ y \:  =  \:  \frac{1}{6}
