 \frac{1}{ \sqrt{x} }  = a \:  \:  \:  \:  and  \:  \:  \:  \:  \: \frac{1}{ \sqrt{y} }  = b \\ 2a + 3b= 2 \:  \: or \:  \: 6a + 9b = 6 \\ 4a - 9b =  - 1 \\ a =  \frac{1}{2}  \:  \:  \:  \:  \: and \:  \:  \:  \:  \:  \:  \:  b =  \frac{1}{3}  \\  \sqrt{x}  = 2 \:  \:  \:  \: and \:  \:  \:  \:  \sqrt{y}  = 3 \\ x = 4 \\ y = 9
