let \: \frac{1}{x + y}  = u \: and \frac{1}{x - y}  = v \\ 44u + 30v = 10 \\ 55u + 40v = 13 \\ by \: solving \: these \:  \: linear \:  \: equations \: we \: get \: \\ u =  \frac{1}{11}  \\ v =  \frac{1}{5}  \\  \frac{1}{x + y}  =  \frac{1}{11}  \\ x + y = 11 \\  \frac{1}{x - y}  =  \frac{1}{5}   \\ x - y = 5 \\  by \: solving \: x + y = 11 \: and \: x - y = 5 \\ x =8 \\ y = 3
